Spring in Mumbai shows up with a steady rise in warmth, longer days, and that unmistakable shift toward higher humidity. You’ll usually see daily high temperatures around 90°F, while lows creep up from the upper 60s to the low 80s as spring rolls on. Honestly, it’s one of the warmest and most humid stretches of the year, and it leads right into monsoon season.
Cloud cover and rainfall change fast during these months. Early spring feels dry, with mostly clear skies, but by late May, rain chances shoot up and the air grows heavy with moisture.
Coastal winds start to pick up, and the Arabian Sea warms into the mid-80s, which just adds to the city’s sticky feel.
If you’re planning to spend time outdoors, get ready for some hot, sticky afternoons. Knowing when the humidity peaks, how rainfall patterns change, and how sea breezes might help (or not) makes it easier to plan your day, whether you’re sightseeing or just getting through daily life.
Overview of Spring Weather in Mumbai
Spring in Mumbai brings steady warmth, rising humidity, and a clear hint that the monsoon isn’t far off. You’ll notice longer days, warmer nights, and more clouds as spring moves on.
Spring Months and Seasonal Timing
Spring in Mumbai usually runs from March through May. Temperatures rise bit by bit, but humidity really ramps up toward the end of the season.
In March, you get average highs around 90°F (32°C) and lows near 70°F (21°C). By the end of May, highs often hit 91–92°F (33°C), and lows hover around 82°F (28°C).
The biggest change happens at night, when evenings feel much warmer than they did a couple months earlier.
Daylight stretches out too. Early March gives you about 11 hours 45 minutes of daylight, but by late May, you’re looking at over 13 hours. Sunrise creeps earlier, sunset pushes later, and evenings seem to last forever.
Rainfall stays minimal in March, but by May, showers start to show up as pre-monsoon activity kicks in. Late spring feels more humid and unsettled compared to the dry start in March.
General Climate Characteristics
Mumbai’s spring climate? It’s hot, humid, and increasingly cloudy. The city’s coastal location along the Arabian Sea shapes both humidity and wind.
Average daytime highs stick in the upper 80s to low 90s°F (30–33°C). Sea breezes help a bit, but nights grow muggy with dew points climbing above 70°F (21°C) by May.
Cloud cover increases from about 17% in early March to nearly 60% by late May. The chance of rain goes up too, from almost none in March to about 1 in 4 days by the end of spring.
Winds shift as spring goes on. Early in the season, breezes blow from the north, but by April and May, they swing westerly, dragging in more moisture. This sets the stage for the heavy June rains.
Comparison With Other Seasons
Spring in Mumbai feels hotter and more humid than winter. Back in January, lows can dip to 66°F (19°C), but spring nights rarely drop below 70°F (21°C). That winter comfort disappears fast once spring hits.
Summer and monsoon months bring way more rain than spring. By July, Mumbai averages over 800 mm (31 in) of rain in just one month, while spring totals are much lower. The difference is pretty dramatic.
Autumn, after the monsoon, is less humid than spring. Skies clear up, rainfall drops, and even though it’s still warm, the air feels drier and more pleasant than the sticky late-spring weather.
So, spring really acts as a bridge—right between Mumbai’s mild, dry winter and that wild, wet monsoon summer.
Average Spring Temperatures
Spring in Mumbai brings steady warmth and rising humidity. Daytime highs land in the upper 80s to low 90s °F, and nights get warmer as summer gets closer.
The change feels gradual, but by late May, the combo of heat and humidity can get uncomfortable.
Daytime and Nighttime Temperature Ranges
During spring, Mumbai’s daytime temps usually hit 88–91°F (31–33°C). Highs rarely fall below 83°F or jump above 97°F. The hottest afternoons pop up in late May, when the sun’s stronger and clouds start to roll in.
At night, temps climb as spring goes on. Early in the season, you might see lows around 70°F (21°C), but by late May, nights often stick near 82°F (28°C).
This small gap between day and night temps means you don’t get much relief after sunset. Most folks rely on air conditioning or ceiling fans to stay comfortable indoors.
Monthly Temperature Trends
Spring in Mumbai runs from March through May, and each month gets a little hotter.
- March: Highs average about 88°F, and nights are around 70°F. It’s the most comfortable part of spring.
- April: Temps rise, with highs near 90°F and lows around 76°F. Humidity starts to creep up.
- May: The hottest month of spring, with highs around 91°F and nights staying warm at 82°F. This is when that pre-monsoon buildup feels most obvious.
By late May, high temps and sticky air make outdoor afternoons a real challenge. Most travelers and locals prefer to get out in the mornings or evenings.
Historic Temperature Extremes
Mumbai’s spring weather usually stays steady, but sometimes it throws a curveball. The highest daily average high hits 91°F on May 21, though rare heat waves can push things up to 97°F.
On the cooler end, spring nights almost never drop below 66°F, even in early March. So you won’t run into cold spells like you might in northern India.
Just for comparison, the city’s hottest day of the year usually comes in late October (highs near 92°F), and the coldest in mid-January (lows around 66°F). Spring lands squarely in the warm-to-hot range, without any wild swings.
Rainfall and Precipitation Patterns
During spring, Mumbai shifts from dry winter toward the wetter months ahead. Rainfall stays low, but you’ll feel humidity and warmer air building up as monsoon season approaches.
Typical Precipitation Levels
From March through May, Mumbai barely sees any rain compared to the rest of the year. March averages less than 1 mm of precipitation, and April isn’t much different, usually recording only 0–1 mm.
By May, rainfall ticks up a bit, averaging 10–15 mm, but that’s still nothing compared to monsoon season. Spring is definitely one of the driest stretches for the city.
| Month | Average Rainfall (mm) |
|---|---|
| March | ~0.5 mm |
| April | ~0.7 mm |
| May | 10–15 mm |
This dry weather means plenty of clear skies and long sunny days, a big contrast to the heavy downpours that take over during the monsoon season.
Frequency of Rainy Days
Rainy days barely happen in spring. March and April usually have 0 to 1 rainy day, so most days stay totally dry.
May brings a small uptick, with about 1–2 rainy days on average.
With so little rain, you can count on outdoor plans not getting ruined by showers. The dry weather also means humidity keeps building, setting the stage for a big change in June.
Travelers love this time for its reliable conditions—no monsoon disruptions, just steady sunshine.
Transition to Monsoon Season
By late May, you’ll start noticing the atmosphere changing. Humidity rises, clouds show up more often, and you might get the occasional pre-monsoon shower.
These showers don’t last long, but they can be intense—a sneak peek at what’s coming.
Mumbai’s monsoon is one of India’s heaviest, bringing over 500 mm of rain in July alone. Spring acts as the buildup, getting the land and air ready for the deluge.
You’ll feel the change most in May, when the first signs of unstable weather hint that sustained monsoon rains aren’t far off.
Humidity and Air Conditions
Spring in Mumbai means rising humidity along with warm days. These conditions really affect how the air feels, both inside and out.
Understanding the humidity and what it does to your body can help you plan for the season.
Relative Humidity Levels in Spring
From March through May, Mumbai’s relative humidity climbs steadily. March averages 65–70%, but by May, it can easily top 80%.
This rise happens as the monsoon gets closer and moisture just hangs in the air.
Mornings usually feel damper than afternoons. Early hours can seem downright muggy, while later in the day, heat disperses some of that moisture.
The mix of high temperatures (around 86–91°F / 30–33°C) and rising humidity makes the air feel warmer than the thermometer says. Even a moderate day can feel sticky.
| Month | Avg. Relative Humidity | Common Range |
|---|---|---|
| March | ~65–70% | 60–75% |
| April | ~75–80% | 70–85% |
| May | ~80%+ | 75–88% |
No wonder late April and May often feel muggy.
Impact on Comfort and Health
High humidity makes it harder for your body to cool off through sweat. In Mumbai’s spring, you might feel overheated even if the temperature isn’t outrageous.
Sweat evaporates slowly, so you end up with sticky skin and not much relief, even in the shade.
Kids and older adults can feel the effects more—heat and humidity add up to extra fatigue. Staying hydrated and laying low during the hottest hours helps.
Indoors, things can feel heavy without good airflow. Fans and open windows help move the air around, and air conditioning, if you have it, makes a real difference.
If you’re out exploring, light clothes and frequent indoor breaks make it easier to handle the muggy air. Knowing how humidity affects you lets you plan your day better.
Sea Temperature and Coastal Effects
Mumbai’s spot on the coast seriously shapes its weather. The sea stays warm, and that steady heat changes how the shoreline feels, when rain shows up, and the general climate near the coast.
Average Spring Sea Temperatures
In spring, the Arabian Sea off Mumbai warms up. Average sea temperatures go from about 27.0°C in March to 30.2°C in May.
This rise matches the season’s jump in air temperature, which hovers in the low to mid-30s during the day.
The water almost never drops below 27°C, so the sea feels warm enough for swimming or just hanging out by the coast.
By late spring, the water can actually be warmer than the night air, keeping evenings humid along the shore.
| Month | Average Sea Temp (°C) |
|---|---|
| March | 27.0°C |
| April | 29.1°C |
| May | 30.2°C |
You’ll notice the biggest change between March and April. This warming sea signals the monsoon’s approach, since all that stored heat starts to play a role in the coming weather shifts.
Influence on Coastal Weather
In spring, the sea warms up and directly shapes Mumbai’s coastal climate. Warm waters make the air heavier and stickier at night, and you’ll definitely notice the humidity.
This humidity keeps evenings from getting too cool, so the weather feels more even all season.
Sea breezes bring in moisture, drifting inland and making mornings a bit hazy. You might spot more clouds, especially as May rolls around.
These little changes hint that monsoon season isn’t too far off.
Warm sea surfaces keep temperatures steady. You won’t see daytime highs shooting much past the mid-30s, and nights usually sit in the upper 20s.
That’s why Mumbai’s spring feels so stable, especially if you compare it to places farther from the coast.
Tips for Visiting Mumbai During Spring
Spring in Mumbai means the heat’s on the rise, humidity kicks up, and by late May, rain might surprise you. You’ll want to prep for sunny days but also be ready for muggy evenings or a quick shower.
What to Pack for Spring Weather
Definitely pack lightweight, breathable clothing—daytime highs often hover around 90°F (32°C). Cotton or linen? Always a good bet for comfort.
A wide-brimmed hat, sunglasses, and sunscreen come in handy if you’re out in the sun for a while.
As the humidity grows, you’ll want a refillable water bottle to stay hydrated.
By late spring, a compact umbrella or light rain jacket really helps, since pre-monsoon showers start popping up.
Pick footwear that’s practical. Sandals or breathable sneakers are great for city walks, but if you’re visiting closer to the rains, water-resistant shoes make more sense.
If you’re near the waterfront in the evening, a light shawl or scarf can make things more comfortable when the breeze picks up.
Mumbai doesn’t need heavy layers in spring, so packing light just makes life easier.
Best Outdoor Activities
Spring feels like the perfect time to wander along Marine Drive or hang out at Girgaum Chowpatty Beach. The evenings, when the air finally cools down a bit, really make these spots come alive.
If you’re up early, try walking in Sanjay Gandhi National Park. The shaded trails there give you a break from the sun, and honestly, the mornings are just quieter.
People love exploring heritage districts like Fort and Colaba before the midday heat hits. If you’re thinking about seeing the Gateway of India or catching a ferry to Elephanta Island, mornings are your best bet for avoiding the worst of the heat.
By late spring, the humidity can get intense, so it makes sense to pick activities where you can duck inside now and then. Shopping arcades, art galleries, and shaded markets offer a good mix of local culture and a chance to cool off.
You’ll also find plenty of festivals and cultural events popping up during spring. It’s a great way to experience Mumbai’s traditions while still enjoying the season.
