Best Time to Visit Mumbai — Month-by-Month Weather, Festivals & Honest Advice

The Short Answer

November to February is the best time to visit Mumbai. Temperatures are comfortable (19-33°C), rainfall is negligible, humidity drops to tolerable levels, and the city's cultural calendar is at its richest -- Diwali, Kala Ghoda Arts Festival, Christmas markets, and New Year celebrations all fall in this window. Hotels are priciest during December and January, but the weather alone justifies the premium.

But here is what most guides won't tell you: every season in Mumbai has genuine appeal. Summer (March-May) is brutally hot but rewards you with deserted tourist sites and hotel rates 30-40% below peak. The monsoon (June-October) is dramatic and disruptive, yet offers experiences -- Ganesh Chaturthi processions, storm-watching on Marine Drive, waterfall treks in the Western Ghats -- that are impossible at any other time of year. Mumbai is not a one-season city. It is a twelve-month city with different personalities depending on when you arrive.

What matters more than picking the "perfect" month is understanding what each season actually delivers so you can pack right, plan activities accordingly, and set your expectations. A well-prepared July trip to Mumbai will be better than an ill-prepared November trip every single time.

The Three Seasons

Winter (November - February) — The Golden Window

This is peak season for a reason. Daytime temperatures range from 29-33°C -- warm but not punishing -- and nighttime temperatures dip to a truly pleasant 17-22°C, which in Mumbai terms feels almost cold. The humidity drops from the monsoon's suffocating 85-95% to a more manageable 60-70%. Rain is virtually nonexistent. The Arabian Sea is calm, the sky is clear, and the air quality is at its annual best (which, by global standards, is still mediocre, but by Mumbai standards, it is refreshing).

This is when Mumbai feels most alive on its streets. Evening walks along Marine Drive are comfortable rather than sweaty. Rooftop bars and restaurants are packed but pleasant. Street food vendors operate at full capacity without the monsoon disruptions. The outdoor festival season is in full swing: Kala Ghoda Arts Festival (February), Christmas bazaars in Bandra (December), Mumbai International Film Festival, and numerous music and cultural events that rely on dry weather and temperate evenings.

The trade-off is crowds and prices. December and January are the most expensive months for accommodation -- expect to pay 40-60% more than the annual average for hotels across all categories. Tourist sites like Gateway of India, Elephanta Caves, and Colaba Causeway are at their busiest. If you are budget-conscious, target November or February instead of the December-January peak. You get nearly identical weather with noticeably lower prices and thinner crowds.

Summer (March - May) — The Furnace

March begins comfortably -- it is essentially an extension of winter with daytime highs around 33°C -- but by April, Mumbai transforms into a furnace. April and May temperatures routinely hit 35-38°C with humidity climbing back above 75%. The combination of heat and humidity creates an oppressive "feels-like" temperature that regularly exceeds 42-45°C. This is not dry desert heat; it is thick, wet, inescapable heat that soaks through your clothing within minutes of stepping outside.

The upside is significant if you can handle the conditions. Tourist numbers plummet to annual lows. Hotel prices drop 30-50% across all categories -- that INR 6,000/night room in Colaba becomes INR 3,500. Restaurants that are impossible to get into during winter have open tables. You can walk through CSMT, the Prince of Wales Museum (now Chhatrapati Shivaji Maharaj Vastu Sangrahalaya), or Elephanta Caves with a fraction of the usual crowd. Domestic flights and trains to Mumbai are cheaper and easier to book.

The practical strategy for summer visits: plan outdoor activities for early morning (6-9 AM) and evening (5-8 PM). Spend the brutal midday hours (11 AM - 4 PM) in air-conditioned museums, malls, restaurants, or your hotel. Carry a water bottle, drink 3-4 liters daily, and apply sunscreen religiously. Holi (March) and the occasional pre-monsoon thunderstorm in late May break the monotony and offer spectacular moments.

Monsoon (June - October) — The Dramatic One

Mumbai's monsoon is not a gentle rain. It is a four-month deluge that dumps an average of 2,200 mm of rainfall on the city -- roughly triple what London receives in an entire year. The monsoon typically arrives in the first or second week of June, hits its furious peak in July and August (500-800 mm per month), and gradually retreats through September and October. Temperatures drop back to 27-32°C, but humidity rockets to 90-100%, making the air feel thick enough to swim through.

The city floods. This is not hyperbole -- it is infrastructure reality. Mumbai was built on seven islands that were gradually connected through reclamation, and its drainage system is chronically overwhelmed during heavy rainfall. Low-lying areas like Hindmata, Sion, King's Circle, and parts of Andheri flood regularly. Local train services -- the city's lifeline -- get suspended during waterlogging events. Flights are delayed or cancelled. Roads become impassable. Every monsoon season brings at least a few days where the city effectively grinds to a halt.

And yet: the monsoon is when Mumbai is at its most visually dramatic and culturally electric. Marine Drive during a fierce storm, with waves crashing over the sea wall and the entire Queen's Necklace shrouded in mist, is one of the most powerful urban landscapes on the planet. The Western Ghats erupt into waterfalls -- Kune, Bhivpuri, Dudhsagar -- all accessible on weekend day trips from the city. Street chai tastes truly transformative when it is pouring outside. And September brings Ganesh Chaturthi, Mumbai's most important festival, when the entire city unites in a ten-day celebration that culminates in one of the largest religious processions on earth.

If you visit during monsoon, you are not making a compromise -- you are choosing a different Mumbai. Just pack waterproof everything, keep your itinerary flexible, and accept that getting drenched is not a possibility but a certainty.

Month-by-Month Breakdown

January

Temperature: 19-32°C. Rainfall: 0 mm. Humidity: 60-65%.

January is Mumbai at its most pleasant. Morning temperatures dip to 19-20°C -- cool enough for Mumbaikars to dramatically pull out sweaters and shawls they own specifically for these six weeks of the year. Afternoons are warm (30-32°C) but the low humidity makes it really comfortable. Republic Day (January 26th) brings parades and cultural programs, particularly impressive at the Gateway of India and along Marine Drive. The sky is clear, the sea is calm, and photography conditions are excellent with soft golden light from about 4:30-6 PM. Hotel prices are elevated but slightly below the December peak as the holiday rush subsides. Expect to pay 30-40% above the annual average for accommodation.

Verdict: Excellent. One of the two best months alongside November. Perfect for first-time visitors.

February

Temperature: 17-33°C. Rainfall: 0 mm. Humidity: 58-65%.

February delivers the coolest nighttime temperatures of the year (17-19°C in the first two weeks), making evening walks along Marine Drive and Bandstand pleasant. The marquee event is the Kala Ghoda Arts Festival -- a nine-day celebration in the Fort district featuring street art installations, live music, dance performances, food stalls, literature events, and craft workshops. The entire Kala Ghoda neighborhood transforms into an open-air gallery, and the atmosphere is electric. Mumbai also hosts its marathon in January or February (dates vary), which partially closes Marine Drive and creates a festive vibe across South Mumbai. Hotel prices begin to ease from peak-season levels by mid-February.

Verdict: Excellent. The Kala Ghoda Festival alone makes this month special. Slightly cooler than January, marginally cheaper.

March

Temperature: 22-34°C. Rainfall: 0 mm. Humidity: 65-70%.

The transition month. Early March still feels like winter's tail end -- comfortable and dry with temperatures rarely exceeding 33°C. By late March, you can feel the heat building. Holi (date varies, usually March) is the highlight: Mumbai celebrates the festival of colors with genuine enthusiasm, particularly in neighborhoods like Juhu, Bandra, and Dadar. Public celebrations with colored powder, water balloons, and music happen across the city. There are also private Holi parties and rain dance events at clubs and hotel pools. The key timing detail: if Holi falls in early March, you get the festival plus comfortable weather. If it falls in late March, add sweat to the equation. Tourist crowds thin noticeably after the first week, and hotel prices drop 10-20% from peak.

Verdict: Good, especially early March. Holi is worth the heat if you time it right.

April

Temperature: 25-35°C. Rainfall: 0-2 mm. Humidity: 70-75%.

April is when Mumbai starts to feel uncomfortable. Daytime temperatures consistently hit 34-35°C, and the rising humidity means the "feels-like" temperature is closer to 40°C by mid-month. The mornings are warm rather than pleasant. Air conditioning becomes less a luxury and more a survival mechanism. On the positive side, this is when Gudi Padwa (Marathi New Year) brings neighborhood celebrations with decorated gudi poles, processions, and community feasts -- a more authentic, less touristy cultural experience than the winter festivals. Tourist sites are noticeably empty. You can walk through the Prince of Wales Museum or the CSMT heritage building without competing for space. Hotel prices are at moderate levels, 15-25% below peak.

Verdict: Average. Workable with smart planning (early morning/late evening outdoor activities), but not ideal for first-timers.

May

Temperature: 27-36°C. Rainfall: 15-20 mm. Humidity: 75-80%.

The hottest month. May in Mumbai is a physical endurance test: temperatures push 35-36°C with humidity at 75-80%, creating a steam-bath atmosphere that makes even short walks exhausting. Pre-monsoon thunderstorms begin to appear in late May -- sudden, violent downpours that last 30-60 minutes and temporarily drop the temperature by 5-7°C, providing fleeting relief. These storms are spectacular to watch from a sheltered vantage point (Marine Drive, a rooftop bar) but can cause flash flooding in low-lying areas. This is the deepest off-season. Hotels offer their lowest rates -- some offer 40-50% discounts and include breakfast or spa credits to fill rooms. If you are on a tight budget and can handle the heat, May delivers maximum Mumbai per rupee.

Verdict: Challenging. Only recommended for budget-focused travelers or those who enjoy tropical heat.

June

Temperature: 26-33°C. Rainfall: 500-600 mm. Humidity: 85-90%.

The monsoon arrives -- typically between June 7th and 15th -- and the city transforms overnight. Temperatures actually drop from May's punishing highs, but the humidity surges to 85-90%, making the air feel saturated. The first rains are celebrated -- Mumbaikars step out to enjoy getting wet after months of heat, street food vendors pivot to monsoon specialties like hot bhajiya (vegetable fritters) and steaming corn on the cob, and the parched landscape turns green within days. But the rains also bring disruption: waterlogging in low-lying areas, delayed trains, diverted flights. The first two weeks of monsoon are often the most unpredictable, as rainfall can swing from torrential to bone-dry day by day. Hotel prices are at off-season lows.

Verdict: For adventurous travelers. The monsoon arrival is exciting, but infrastructure disruptions are real.

July

Temperature: 25-31°C. Rainfall: 700-850 mm. Humidity: 90-95%.

Peak monsoon. July dumps more rain on Mumbai than any other month -- an average of 700-850 mm, with individual days capable of delivering 200+ mm in a single downpour. This is when the city's flood risk is highest. The suburban rail network gets disrupted multiple times per month. Roads in areas like Sion, Dadar, and Andheri can flood to knee or waist depth during extreme events. Flights at Chhatrapati Shivaji Maharaj International Airport face frequent delays and occasional diversions. The rain is not continuous -- there are breaks of a few hours or even a full day -- but when it rains, it rains with terrifying intensity. Despite all this, the city does not shut down. Restaurants stay open. Street food vendors set up under tarps. The Western Ghats are at their most spectacular: waterfalls at full force, every surface covered in green moss, visibility shifting between clear and mystical fog. Weekend trekking trips to Lonavala, Matheran, or Malshej Ghat are popular among locals and offer some of the most beautiful landscapes near Mumbai.

Verdict: Difficult for tourism. Only recommended if you specifically want the monsoon experience and have a flexible itinerary.

August

Temperature: 25-30°C. Rainfall: 550-700 mm. Humidity: 90-95%.

August is July's slightly less intense twin -- still very wet (550-700 mm), still prone to flooding, still humid enough to wring out the air. Independence Day (August 15th) is celebrated with flag-hoisting ceremonies, cultural programs, and patriotic fervor at Gateway of India and across the city. But the real story of August is the build-up to Ganesh Chaturthi, which falls in late August or early September (2026 date: August 22nd). Neighborhoods across the city begin preparing weeks in advance -- constructing pandals (temporary shrine structures), commissioning Ganesh idols from artisans in Pen and Lalbaug, and organizing community celebrations. The energy is palpable even before the festival officially begins. Janmashtami (celebrating Krishna's birthday) also falls in August, with its famous dahi handi competitions where human pyramids form to break hanging clay pots -- a spectacular and uniquely Mumbai tradition, especially intense in Dadar, Worli, and Thane.

Verdict: Wet but culturally rich. If Ganesh Chaturthi falls in August, it becomes one of the most memorable months to visit despite the rain.

September

Temperature: 25-31°C. Rainfall: 350-450 mm. Humidity: 85-90%.

September is defined by one event: Ganesh Chaturthi. When it falls in September (as it does in 2026, with visarjan on September 1st), this is the month you visit Mumbai if you want to see the city at its cultural zenith. Over 200,000 Ganesh idols are installed across the city, from modest household shrines to towering 20-foot installations in Lalbaug and Parel. The ten-day festival culminates in the visarjan procession, when idols are carried through the streets to Girgaon Chowpatty, Juhu Beach, and other immersion points, accompanied by drumming, dancing, and ecstatic chanting. Millions of people fill the streets. It is chaotic, emotional, deafening, and utterly unforgettable. The rain is still present but begins to taper -- September averages 350-450 mm, noticeably less than July's deluge, and the breaks between showers grow longer.

Verdict: Essential for Ganesh Chaturthi. The rain is manageable if you have waterproof gear.

October

Temperature: 24-34°C. Rainfall: 60-100 mm. Humidity: 75-80%.

The monsoon retreats. October marks the transition from wet to dry, with rainfall dropping dramatically to 60-100 mm -- most of which falls in the first two weeks before the monsoon officially withdraws. By mid-October, Mumbai begins to dry out, the humidity starts its seasonal decline, and clear skies return. This is underrated as a travel month. The landscape is still lush and green from four months of rain, the light is beautiful for photography (warm afternoon glow without the winter haze), and tourist crowds haven't yet arrived for peak season. Navratri (nine nights of dance, music, and worship) typically falls in October, with garba and dandiya raas celebrations across the city -- commercial events at venues like NESCO or MMRDA grounds, and neighborhood community celebrations that are more authentic. Diwali sometimes falls in late October (2026: October 20th), transforming the city with millions of oil lamps, fireworks, and some of the best sweets you will eat anywhere in India.

Verdict: Very good. An underrated sweet spot -- post-monsoon freshness, festivals, fewer tourists, reasonable prices.

November

Temperature: 21-34°C. Rainfall: 10-15 mm. Humidity: 60-70%.

The consensus best month, and it earns the title. The monsoon is over, the humidity has dropped, nighttime temperatures fall to a comfortable 21-23°C, and the sky is reliably clear. Rainfall is effectively zero (10-15 mm is one light shower at most). The post-monsoon landscape is still green, the Arabian Sea is calm for Elephanta Caves ferry trips, and the air quality is at its annual best before winter pollution settles in. Diwali occasionally falls in early November (depending on the year), and even when it does not, the festive energy lingers. Hotel prices are rising from off-season lows but haven't yet hit December's peak -- mid-November is the sweet spot for value. This is the month to come if you want perfect weather, manageable crowds, and full access to every outdoor activity Mumbai offers.

Verdict: The best month. Perfect weather, post-monsoon beauty, pre-peak-season value.

December

Temperature: 19-33°C. Rainfall: 0 mm. Humidity: 58-65%.

Peak tourist season. December weather is virtually identical to November's -- warm days, cool evenings, zero rain, low humidity -- but the crowds and prices are at their annual maximum. Christmas is celebrated with particular enthusiasm in Bandra, which has a large Catholic community: Hill Road and Linking Road light up with decorations, midnight mass at Mount Mary Church draws thousands, and neighborhood bakeries produce extraordinary quantities of plum cakes, marzipan, and kulkuls. New Year's Eve is a citywide event -- hotel rooftop parties, nightclub events, and the informal but massive public gathering at Marine Drive and Gateway of India to watch fireworks at midnight. Hotels charge premium rates: expect to pay 50-70% above the annual average, with popular properties in Colaba and Bandra booked out weeks in advance. Book accommodation a minimum of 4-6 weeks ahead for December travel.

Verdict: Excellent weather, peak prices. Book early and budget 40-60% more than you would in November.

* September crowds surge specifically during Ganesh Chaturthi. Outside the festival, the city is quiet.

Festivals & Events Calendar

Mumbai's festival calendar is relentless and spectacular. These are the events worth planning your trip around.

Ganesh Chaturthi (August-September). Mumbai's soul festival. For ten days, the city installs over 200,000 Ganesh idols in homes, neighborhoods, and public pandals (temporary shrines). The most famous pandals -- Lalbaugcha Raja, Mumbaicha Raja, and Ganesh Galli -- draw millions of visitors who queue for hours to receive darshan (blessing). The visarjan (immersion) on the final day is the climax: processions carrying idols of all sizes wind through the streets to the sea, accompanied by dhol-tasha drums, dancing, and chanting "Ganpati Bappa Morya." The largest idols travel through Lalbaug and Parel to Girgaon Chowpatty for immersion. The procession can last from early morning until well past midnight. 2026 dates: August 22nd (start) to September 1st (visarjan). Book hotels 2-3 months ahead. Road closures and massive crowds make transport unpredictable -- use local trains and walk.

Diwali (October-November). The festival of lights transforms Mumbai into a glittering spectacle. Every home, shop, and building is illuminated with oil lamps, candles, and electric lights. Firework displays (though increasingly restricted due to pollution regulations) light up the skyline. The real draw is the sweets: every neighborhood bakery and mithai shop produces its finest work -- kaju katli, motichoor ladoo, gulab jamun, and specialty dry fruit barfi. The markets in Dadar, Crawford Market, and Lalbaug overflow with flowers, decorations, and gift boxes. Dhanteras (two days before Diwali) is the big shopping day for gold and silver. 2026 date: October 20th. Hotels charge premiums during Diwali week, particularly in South Mumbai.

Holi (March). The festival of colors is celebrated across Mumbai with colored powder (gulaal), water balloons, bhang lassi (cannabis-infused drinks, legally sold during Holi), and community gatherings. The most energetic celebrations happen in residential neighborhoods -- Juhu, Bandra, Dadar, and the chawls of Central Mumbai. Commercial Holi parties at clubs and hotels offer a more controlled (and photogenic) experience for tourists. Jogeshwari and Marol have large North Indian populations that celebrate with particular intensity. 2026 date: March 14th. Tip: wear clothes you are prepared to throw away, protect your phone in a zip-lock bag, and apply coconut oil to your skin and hair before going out -- it makes the color easier to wash off.

Kala Ghoda Arts Festival (February). Mumbai's premier cultural event is a nine-day celebration in the historic Fort/Kala Ghoda district that turns the neighborhood into an open-air gallery. Street art installations, sculpture, photography exhibitions, live music and dance performances, stand-up comedy, literature panels, craft bazaars, and food stalls occupy every available space. The festival is free to attend and draws enormous crowds -- weekday visits are more manageable. It is curated seriously, featuring established and emerging artists, and the quality is consistently high. 2026 dates: typically first two weeks of February (exact dates announced in January). This is reason enough to plan a Mumbai trip around February.

Christmas and New Year's Eve (December). Bandra's Catholic community transforms Hill Road and surrounding streets into a festive wonderland starting in early December. Midnight mass at Mount Mary Basilica and the Bandra churches draws thousands of worshippers and spectators. The neighborhood bakeries -- particularly the tiny home-based operations in Bandra East and Ranwar village -- produce spectacular plum cakes, wine-soaked fruitcakes, and traditional East Indian sweets. New Year's Eve is a citywide event: the Gateway of India and Marine Drive fill with hundreds of thousands of revelers, hotels host premium-priced rooftop parties (INR 5,000-25,000 per person), and the nightclubs of Bandra, Juhu, and Lower Parel run until dawn. Book NYE accommodation and events by mid-November at the latest.

Best Time for Specific Activities

Different activities have different optimal windows. Here is the honest breakdown by interest:

Street food. November to February, no contest. Cooler temperatures make standing at crowded stalls far more comfortable, hygiene risks are at their lowest (less bacterial growth in food, less contamination from flooding), and seasonal specialties appear: roasted peanuts and sweet potato on the streets, fresh strawberries from Mahabaleshwar at Juhu Beach, undhiyu during Makar Sankranti, and the extraordinary diversity of Muslim street food on Mohammad Ali Road during Ramadan (timing varies by the Islamic calendar). The monsoon months (July-September) require more caution -- waterlogging can contaminate street cooking areas, and vendors sometimes use standing water for washing. Stick to high-turnover stalls and freshly cooked items.

Photography. Late October and November are the photographer's months. The post-monsoon air is the clearest it gets all year, the landscapes retain their monsoon green, afternoon light is warm and golden without the haze that builds up by January, and the crowds are thin enough to shoot architecture and street scenes without constant obstruction. The hour before sunset (5:00-6:00 PM in winter) along Marine Drive produces the best light for the Queen's Necklace shot. Monsoon photography is spectacular but demands weather-sealed gear and quick reflexes -- the storm light over the Arabian Sea and the cascading Western Ghats waterfalls are extraordinary subjects.

Nightlife. Year-round, with seasonal peaks. Mumbai's bar and club scene does not have an off-season. However, the outdoor rooftop bars (Aer at Four Seasons, Asilo at St. Regis, Dome at Intercontinental) are best from November to February when evenings are cool and dry. During monsoon, the rooftop venues either close or cover up, pushing the scene to indoor clubs. December and New Year's Eve bring special events but also inflated cover charges (INR 3,000-10,000 at popular venues). The best balance is November: everything is open, the weather is perfect for rooftop drinking, and prices haven't hit holiday levels.

Beaches. November to February for Juhu, Versova, and Aksa beaches. The sea is calm, the sand is clean (post-monsoon cleanup), and the evening breeze off the Arabian Sea is pleasant without being cold. Beach visits during monsoon are not recommended -- rough seas, contaminated water, and the risk of high tide surges make swimming dangerous. The lifeguard service at Juhu and Girgaon Chowpatty operates year-round but is most active in winter. Even in peak season, Mumbai beaches are not swimming beaches in the tropical-resort sense -- the water quality is poor. The beach experience here is about walking, eating chaat and bhelpuri at sunset, and watching cricket games on the sand.

Trekking and day trips. Two distinct seasons, two different experiences. Monsoon (July-September) is the prime trekking season for waterfall chasers and green-landscape lovers: Dudhsagar, Kune, Bhivpuri, and the forts of Rajmachi, Lohagad, and Visapur are at their most spectacular, with water cascading off every cliff and the Western Ghats blanketed in emerald. The trails are slippery and leeches are present -- wear proper trekking shoes and full-length trousers. Winter (November-February) is better for fort treks and panoramic views: Sinhagad, Rajgad, Harishchandragad, and Kalsubai offer clear visibility, comfortable temperatures, and dry trails. The sunrise from Kalsubai (Maharashtra's highest peak, 1,646 m) on a clear January morning is one of the great weekend experiences accessible from Mumbai.

Hotel Pricing Patterns

Understanding Mumbai's hotel pricing cycle can save you thousands of rupees. The pattern is predictable and consistent across all categories from hostels to luxury hotels.

Peak season (December-January): Prices are 40-70% above the annual average. A mid-range room in Colaba or Bandra that normally costs INR 4,000-5,000 will be listed at INR 6,000-8,000. Budget dorms that run INR 600-800 will be INR 1,000-1,400. Luxury properties like the Taj Mahal Palace and Trident charge rack rate with zero flexibility. December 24-January 2 is the absolute peak -- New Year's Eve pricing can be double the December 15th rate at the same property. Book 6-8 weeks in advance for December-January stays, or accept significantly limited options.

Shoulder season (February-March, October-November): The sweet spot for value. Prices are 10-20% above average -- noticeably cheaper than December-January but still reflecting good-weather demand. Availability is better, and many hotels offer direct-booking discounts of 5-10% if you book through their website rather than OTAs (MakeMyTrip, Booking.com, Agoda). The best deals are in the first two weeks of November and the last two weeks of February.

Off season (April-September): The bargain window. Prices drop 25-50% below the annual average. This is when the apps and aggregators shine -- Booking.com, Agoda, and MakeMyTrip all run monsoon promotions with additional 10-20% off already-reduced rates. Walk-in rates at mid-range hotels can be negotiated to 30-40% below the listed price during monsoon, especially midweek. Even the luxury tier offers packages: monsoon-season stays at the Taj, Trident, or Four Seasons regularly include breakfast, spa credits, or complimentary upgrades. The lowest absolute prices are in July and August.

Festival premiums: Ganesh Chaturthi (August-September) creates a localized spike -- hotels in Central Mumbai (Lalbaug, Parel, Dadar) charge more than usual due to domestic tourists visiting for the festival, but properties in South Mumbai and the suburbs are unaffected. Diwali week sees a 10-20% bump across all areas. New Year's Eve is the single most expensive night of the year for Mumbai hotels.

Booking lead times: For peak season (December-January), book 6-8 weeks ahead. For shoulder season (October-November, February-March), 3-4 weeks is sufficient. For off season (April-September), same-week bookings are usually fine -- availability is ample and last-minute rates are often the best rates. For festival weeks (Ganesh Chaturthi, Diwali, NYE), book 8-12 weeks ahead regardless of the season those festivals fall in.
