When you picture fall in Mumbai, maybe you imagine heavy rains hanging around from the monsoon or those hot, sticky afternoons along the coast. But honestly, the weather turns pretty fast—skies clear up, humidity drops, and temperatures settle into something much more comfortable.
Fall in Mumbai means warm days, cooler nights, and way less rain. It’s often one of the best times of the year to get out and enjoy the city.
You’ll usually see daily highs in the upper 80s to low 90s Fahrenheit, with nights cooling off into the low 70s. The air loses that muggy feeling as the weeks go by, and rain goes from regular September showers to almost nothing by late November.
There’s more sunshine too, so you get brighter days and better views of the Arabian Sea.
This mix of warmth, lower humidity, and longer dry spells shapes everything from outdoor plans to how you get around. Maybe you want to explore Mumbai’s neighborhoods, hang out by the waterfront, or just get a feel for the city’s seasonal rhythm—knowing what fall brings will definitely help you make the most of it.
Overview of Fall Weather in Mumbai
Fall in Mumbai marks a real shift from heavy monsoon rains to clearer skies. Temperatures stay warm, humidity drops, and rainfall falls off fast, so things feel a lot better than during the monsoon.
Typical Fall Climate Characteristics
During fall, daily highs in Mumbai start around 86°F (30°C) in early September and climb to about 90°F (32°C) by late November. Nights cool off from about 78°F (25°C) to 71°F (22°C), so you get warmer days and milder nights.
Rain just drops off a cliff. In early September, you might see about 12 inches (300 mm) of rain in a month, but by November, it’s down to around 0.2 inches (5 mm). The odds of a wet day go from nearly 60% to just 3%.
Clouds thin out too. Early fall skies are mostly cloudy about 70% of the time, but by late November, clear or partly clear days take over. Humidity follows the same pattern, shifting from muggy to much more comfortable.
This combo of warmer days, cooler nights, and drier air makes fall a great season for getting outside in Mumbai.
Comparison to Other Seasons
Compared to summer, fall feels a lot less stifling thanks to the lower humidity. Summer highs might be similar, but the sticky air and constant downpours make it rough.
Winter in Mumbai is cooler, with highs around 86°F (30°C) and lows near 66°F (19°C) in January. Fall sits in between the wet monsoon and the milder winter, giving you that sweet spot of warmth and increasing dryness.
Spring is pretty quick and can get hot, with rising temps before the monsoon hits. Fall, on the other hand, is steadier, with fewer wild swings.
If you stack fall up against monsoon season, the difference is huge. Monsoon months dump 20–30 inches (500–750 mm) of rain in July and August, but by November, rainfall is almost gone.
Influence of Monsoon Transition
The retreat of the southwest monsoon shapes Mumbai’s fall weather. As the rains fade in September, you still get high humidity and the odd shower, but things improve fast.
By October, the monsoon winds die down, and drier air rolls in. Winds shift from west early in fall to north and east by the end, and average speeds slow from about 10 mph in September to 7 mph in November.
With less rain and fewer clouds, you get more sunshine. Days get a bit shorter, but the skies are clearer and brighter. Sea surface temps near Mumbai hold steady around 82°F (28°C), keeping the coast nice and warm.
This transition signals the end of the year’s wettest stretch and paves the way for a cooler, drier winter.
Average Fall Temperatures
In fall, Mumbai’s temperatures slide from the leftover heat of the monsoon toward milder, less humid days. You’ll notice warmer afternoons, cooler nights, and a steady drop in both clouds and rain as fall moves along.
Daytime and Nighttime Temperature Ranges
Early in the season, daytime highs sit around 86°F (30°C) and slowly rise to about 90°F (32°C) by late October. Some days, you’ll see temps briefly hit 92–96°F (33–36°C), especially late in October.
Nights cool off more. Lows drop from about 78°F (26°C) at the start of fall to 71°F (22°C) by late November. It’s rare for nighttime temps to dip below 65°F (18°C).
This difference between warm days and cooler nights makes evenings way more comfortable than in summer. Lower humidity also means it doesn’t feel as muggy, even if the air’s still warm.
Monthly Temperature Trends
September kicks off with warm, humid weather, averaging 86°F (30°C) by day and 78°F (26°C) at night. In October, daytime highs bump up to 88–90°F (31–32°C), while nights cool to about 74°F (23°C).
By November, you’ll notice the biggest change. Afternoon highs still reach 87–89°F (31°C), but nights fall to 71°F (22°C), so evenings feel the nicest all season.
| Month | Avg High °F (°C) | Avg Low °F (°C) |
|---|---|---|
| September | 86 (30) | 78 (26) |
| October | 88–90 (31–32) | 74 (23) |
| November | 87–89 (31) | 71 (22) |
These shifts show how the city moves from the monsoon’s lingering warmth toward the drier, cooler winter.
Temperature Comparison with Annual Averages
Mumbai’s mean annual temperature is about 82°F (28°C), with average highs around 89–90°F (32°C) and lows near 75°F (24°C). Fall temps stick close to these averages but give you slightly cooler nights than the yearly norm.
The hottest stretch comes in late May and early June, with highs often topping 93°F (34°C). The coolest time is January, when daytime highs sit near 86°F (30°C) and lows drop to about 66°F (19°C).
So, fall lands right in the middle of Mumbai’s climate curve. You get daytime warmth like the annual average and noticeably better nights than in summer or monsoon.
Rainfall and Humidity Patterns
In fall, Mumbai moves from the heavy monsoon rains to much drier days. Rainfall drops off quickly, but humidity can still stick around and affect how comfortable you feel, even under clearer skies.
Post-Monsoon Rainfall in Fall
By late September, the southwest monsoon starts to retreat. Rain totals drop compared to July and August, but October can still bring the odd shower. Historical data shows October averages about 65–90 mm of rain, while November usually gets less than 20 mm.
You might still get a few heavy downpours in early October, especially in central and suburban areas. These are often short but can cause local flooding if they hit during high tide. By November, rain is rare and most days stay dry.
The change from monsoon to post-monsoon makes a big difference in daily life. Roads clear up, outdoor plans get easier, and travel disruptions pretty much fade away. If you visit, expect early fall to feel humid with the odd storm, but late fall is much more stable.
Average Humidity Levels
Humidity in Mumbai stays high even after the rains let up. October usually sees 70–80% relative humidity, especially in the mornings. By November, it eases a bit but still sits above 60%.
You’ll notice evenings can feel sticky, especially when winds are light. High humidity makes temps in the low 30s °C feel warmer than they are. Most homes and hotels use air conditioning or ceiling fans to deal with the damp air.
Even though humidity hangs on, it does drop through fall, so comfort improves. By late November, outdoor sightseeing gets a lot easier, and the air doesn’t feel nearly as oppressive as during peak monsoon.
Rainy Days and Dry Spells
The number of rainy days falls fast after September. In October, expect about 3–5 wet days, compared to over 20 in July. By November, rainy days are rare—maybe 0–1 day all month.
Longer dry spells mean more reliable sunshine. Clear November skies also bring more daily sunshine hours, so it’s a great time for outdoor travel and festivals.
Early fall can still surprise you with a sudden shower, but the overall trend is toward dry, predictable weather. This shift signals the end of the wet season and the start of Mumbai’s more comfortable travel stretch.
Sunshine and UV Index During Fall
In fall, Mumbai’s days get a bit shorter, but sunlight stays strong. The UV index remains high, so you’ll want to be careful if you’re out for long stretches.
Average Daily Sunshine Hours
As fall moves from September to November, daylight shrinks. Early September gives you about 12.5 hours of daylight, but by late November, it’s just over 11 hours.
You’ll actually see more sunshine than during the monsoon, since clouds break up a lot. September can be partly cloudy, but by late November, most days are clear or mostly clear.
On average, you get about 7 to 9 hours of sunshine per day during fall. That’s a big plus for sightseeing and outdoor plans compared to the rainy months.
Clear skies mean stronger midday sun, so even if days are shorter, the sunlight is more reliable. If you’re planning to be outside, mornings and late afternoons are usually the most comfortable.
UV Index Trends in Fall
The UV index in Mumbai stays in the high to very high range all through fall. In September, it often peaks at 9 to 10—that’s pretty intense. By November, it drops a bit but usually sits between 7 and 8.
You can get sunburn pretty fast if you’re out midday without protection. Use sunscreen, sunglasses, and protective clothing to play it safe.
Unlike places where fall means lower UV, Mumbai’s tropical spot keeps the sun angle strong all year. Even on hazy or partly cloudy days, those UV rays can get through and cause skin damage.
If you’re hanging out by the coast or on the water, remember that reflection off the sea can boost UV exposure. A few simple precautions go a long way so you can enjoy the clear skies without regret later.
Wind and Sea Conditions
In fall, Mumbai’s winds shift from strong monsoon gusts to lighter breezes, and the Arabian Sea settles down after the heavy rains. You’ll find calmer seas than in summer, though conditions can still change with wind direction and water temperature.
Prevailing Wind Patterns
During fall, Mumbai’s winds mainly come from the west and northwest. They’re much weaker than the monsoon winds you get in summer. Average speeds run between 2 and 9 mph, with gusts sometimes hitting 11 mph.
With drier air after the monsoon, skies clear more often. The winds feel less humid and more refreshing outdoors. Fewer clouds mean steadier breezes instead of sudden shifts.
If you’re planning coastal activities, the lighter winds are generally safe, but you might still see brief changes in direction. Small boats and ferries usually run smoothly, though it’s smart to check the daily forecast if you’re heading out on the water.
Sea Temperature and Coastal Effects
The Arabian Sea near Mumbai stays pretty warm through the fall. Water temperatures usually sit between 27°C and 29°C (81°F to 84°F).
This warmth tends to keep sea conditions stable, so you’ll often see gentler waves, especially when you compare it to the wild monsoon months.
Steady sea temperatures make swimming and other beach activities possible. Most beaches stay open, but some spots still get currents.
It’s always smart to check the safety flags before you jump in.
Humidity drops off after the rainy season, so the coastal air feels lighter. Evenings by the shore get a lot more comfortable, with milder breezes and calmer surf.
Warm water and softer winds combine to create good conditions for relaxing or taking a short boat ride.
Historical Weather Data and Long-Term Trends
Mumbai’s fall climate clearly shifts with the seasons, showing changes in temperature, rainfall, and humidity. Long-term records show how the city moves from monsoon into a drier, clearer stretch. Sometimes, past weather surprises have really shaken up daily life too.
Accessing Historical Fall Weather Data
You can dig up reliable historical weather data for Mumbai from climate records going back to the early 1900s. These records track annual averages for temperature, rainfall, humidity, and wind. They give you a pretty good idea of how fall has changed over the years.
Average fall highs go from 86°F in September to 90°F in late October. Lows drop from 78°F to 71°F.
Rainfall drops quickly, falling from about 13 inches in September to less than 1 inch by November. That sharp decline really signals the end of monsoon and the start of the dry season.
Here’s a simple table for reference:
| Month | Avg High | Avg Low | Rainfall (approx.) |
|---|---|---|---|
| September | 86°F | 78°F | 13 in |
| October | 90°F | 75°F | 3-4 in |
| November | 88°F | 71°F | <1 in |
Most of these numbers come from decades of data at Chhatrapati Shivaji International Airport, which serves as the main weather station for the city.
Significant Fall Weather Events
Usually, fall weather stays steady, but history shows that some years have thrown curveballs. For instance, late-season monsoon bursts in September have flooded low-lying areas.
These events don’t happen as often as in July or August, but when they do, travel and daily routines get thrown off.
Early October has seen strong winds, though average speeds settle down to about 7–10 mph as the season goes on. Sometimes, rare cyclonic storms in the Arabian Sea push extra moisture inland, dumping heavy rain even after the monsoon should be over.
Humidity plays a big part too. In September, almost every day feels muggy, but by November, that drops to about 37%. The air finally gets more comfortable.
That shift is a big reason why fall feels like a bridge between Mumbai’s rainy and dry seasons.
Travel and Lifestyle Considerations in Fall
During fall, Mumbai gets warm days, cooler nights, and a sharp drop in rain compared to the monsoon. Lower humidity and clearer skies make outdoor activities way more comfortable, and traveling around the city isn’t as much of a hassle.
Best Activities During Fall
You can finally get out and see Mumbai in the fall, since the skies clear up and the rains let up. Favorite spots like Marine Drive, Gateway of India, and Elephanta Caves are much easier to visit without worrying about sudden downpours.
Cultural events and festivals pop up during this season, so it’s a great time to check out local traditions. Diwali usually lands in late October or November, lighting up the city with celebrations, markets, and a lot of energy.
The beaches—like Juhu and Girgaum Chowpatty—feel nicer with less humidity. The sea might still get a little rough, but cooler evenings draw plenty of people to the coast.
If you’re into nature, Sanjay Gandhi National Park opens up a bit more in fall. Trails dry out, and the weather actually makes walking or short hikes enjoyable.
What to Pack for Fall Weather
Pack light, breathable clothes for Mumbai’s daytime heat. Temperatures usually climb into the upper 80s or even low 90s °F (about 30–33°C).
Cotton shirts, linen tops, and loose pants help you stay comfortable.
You might want a light jacket or sweater for evenings, since lows sometimes drop to the low 70s °F (21–23°C).
Rain isn’t much of a problem after September, so you can skip the heavy rain gear. Still, a compact umbrella can come in handy, especially early in the season.
Bring comfortable walking shoes if you plan to wander the city’s streets or markets. Sunglasses, sunscreen, and a hat really help with that strong midday sun.
If you’re visiting religious sites, remember to pack modest clothing that covers your shoulders and knees. That way, you’ll respect local customs and still feel comfortable in the weather.
