Packing is easy—bring lightweight cotton for the day, and maybe a layer or two for the evenings.

Around Christmas, Mumbai stays warm in the day but never gets uncomfortably hot. Daytime highs average about 30–31°C (86–88°F), which is pretty typical for winter here.
The heat isn’t as harsh as in April or May, so sightseeing and walking outside are more pleasant.
At night, temperatures drop to 18–20°C (64–68°F). After sunset, the cooler air feels refreshing.
You might want a light sweater if you’re by the water or out late.
Humidity stays lower than during the monsoon, usually between 55% and 65%. The air doesn’t feel sticky, even with the sun out.
Rainfall is almost nonexistent, so you can leave the umbrella at home.

Temperature Fluctuations Throughout December
December in Mumbai doesn’t change much temperature-wise. Early in the month, highs might reach 32°C (89°F), but by late December, they settle near 30°C (86°F).
Nights get a bit cooler as the month goes on, with lows in the upper teens Celsius.
Usually, the difference between day and night temperatures is about 10–12°C (18–22°F). You’ll notice warm afternoons and cooler evenings.
You might want to wear different clothes for daytime and nighttime plans.
December temperatures stay steady—no sharp rises or sudden drops. This makes it one of the easiest times of year to plan outdoor events, day trips, or evening gatherings without worrying about extreme heat or rain.
Rainfall and Humidity Levels
In late December, Mumbai’s weather is shaped by the dry season. Rainfall almost disappears, and humidity levels sit at moderate levels compared to the peak monsoon.
Together, these factors make outdoor activities and travel much more comfortable.
Precipitation Patterns in December
Rainfall in Mumbai during December barely registers. On average, the city records just about 5 mm (0.2 inches) for the whole month.
Most days stay dry, and you’re unlikely to run into showers during your visit.
The southwest monsoon retreats by October, so by Christmas, Mumbai is deep into its dry season. Wet weather is rare.
You’ll usually see zero or maybe one rainy day in December, making it one of the driest months here.
Unlike monsoon season, you don’t need to plan around flooding or waterlogged roads.
This dry spell means sightseeing, beach visits, and outdoor events go ahead without sudden downpours. No need for rain gear—more room in your bag for other things.
Humidity Averages During the Christmas Period
Humidity in December drops compared to summer and monsoon, but it doesn’t get bone-dry. Average relative humidity sits around 60–65%, which most travelers find comfortable.
You might feel a little dampness in the mornings, but it’s not overwhelming. By afternoon, humidity drops further, especially with a light sea breeze along the coast.
This is a huge contrast to July, when humidity can hit 85–86%. In December, you avoid the sticky, oppressive air that dominates the monsoon.
Because of this, you can enjoy both indoor and outdoor spaces without feeling weighed down.
Light, breathable clothing works well, and you won’t need to worry about mold or dampness like you would in wetter months.
Sunshine and Cloud Cover
In late December, Mumbai’s weather brings cooler temperatures and lower humidity than the monsoon months. Expect shorter days, moderate sunshine, and a mix of clear and partly cloudy skies.
Average Daily Sunshine Hours
During Christmas, Mumbai averages about 7 to 8 hours of sunshine each day. That’s less than the peak months, but still plenty for outdoor plans.
December skies are generally clearer than in the monsoon, when heavy clouds block sunlight for weeks.
Lower humidity helps too, making the sunshine feel pleasant rather than oppressive.
Here’s a quick look at sunshine hours across the seasons:
| Month | Avg. Sunshine Hours/Day |
|---|---|
| January | ~8 |
| May | ~10 |
| July | ~2–3 |
| December | ~7–8 |
December offers more consistent sunshine than the rainy season, though not as strong as summer. You get comfortable daylight without the intensity of pre-monsoon heat.
Frequency of Partly Cloudy Days
Around Christmas, partly cloudy days show up fairly often in Mumbai. Skies aren’t as overcast as in July and August, but you’ll still see some light cloud cover on several days.
These clouds usually drift in during the afternoon and rarely bring rain. Instead, they soften the sunlight and make it nicer for walking, sightseeing, or eating outdoors.
Compared to the monsoon, when clouds rule the sky, December feels much clearer.
You might get about 10 to 12 partly cloudy days in the month, but most of those still offer long stretches of sunshine.
This mix of clear skies and light clouds makes December a reliable month for outdoor plans in Mumbai.
Wind and Air Quality Conditions
In late December, you’ll notice calm winds and mild breezes in Mumbai. Air quality, though, can shift depending on pollution levels and weather.
These conditions affect how comfortable you feel outside. If you’re sensitive to air pollution, it’s worth paying attention.
Typical Windspeed and Direction
December falls in Mumbai’s dry season, so winds usually stay light. Average wind speeds hover around 1 m/s (about 3.6 km/h or 2.2 mph)—that’s barely enough to move tree leaves.
You’ll probably find the air still, especially mornings and evenings. Breezes mainly come from the north and northeast, thanks to land breezes heading toward the sea.
During the day, a weak sea breeze might show up, but it’s gentle. Unlike monsoon months, when winds can pick up, December feels calm and easy for outdoor activities.
Air Quality Considerations in December
Air quality in Mumbai during December can be a concern. Little rain and calm winds let pollutants like vehicle exhaust, industrial emissions, and dust build up in the lower atmosphere.
This often leads to moderate to poor air quality, especially in central or high-traffic areas.
Humidity drops compared to the monsoon, so the air doesn’t get “washed” as much. Mornings may feel hazy, and visibility can dip a little.
Sensitive groups—kids, older adults, and those with respiratory issues—might feel discomfort on days when particulate matter spikes.
If you’re planning to be outside, check daily air quality reports. Coastal areas and open spaces usually have cleaner air than crowded inner neighborhoods.
Carrying a mask or avoiding peak traffic hours can help reduce the effects of pollution.
Sea and Water Temperatures
In late December, the Arabian Sea off Mumbai stays warm and steady. Swimming and water activities feel inviting, not chilly.
Average Sea Temperature
December sea temperatures along Mumbai’s coast usually range from 25°C to 27°C (77°F to 81°F). Recent data shows the monthly average sits close to 26°C, with only small changes day to day.
The highest readings in December reach about 27.5°C, and the lowest hover near 24.5°C. You probably won’t notice much difference in water warmth from one day to the next.
Compared to the hot and humid monsoon, December waters feel milder but are still plenty warm for a swim.
Sea temperatures don’t drop much at night, so you get steady warmth all day.
Suitability for Swimming and Water Activities
You can swim comfortably in Mumbai’s waters during December—no wetsuit needed. The sea is warm enough for long swims, and you’re unlikely to feel cold even after sunset.
Calm conditions make December safer for casual swimming. Rainfall is minimal and winds are light, so rough waves are rare.
If you’re thinking about snorkeling, paddleboarding, or boating, the steady water temperature supports a great outing.
Just remember, the sun still feels strong, so sunscreen and staying hydrated are smart moves.
Travel Tips for Visiting Mumbai at Christmas
December in Mumbai usually brings warm, dry days and cooler evenings. Honestly, it’s probably one of the most comfortable times to explore the city.
You’ll see mostly sunny skies, barely any rain, and the sea stays calm. That means you can actually enjoy outdoor sightseeing and catch seasonal events without much hassle.
Recommended Clothing and Packing Essentials
During the day, temperatures often hover between 28–32°C (82–90°F). Nights can dip to 18–20°C (64–68°F), so you might want to throw a light sweater or sweatshirt in your bag for evenings. If you’re heading to the waterfront, expect those breezes to feel a bit chilly.
I always recommend packing light cotton clothes for daytime adventures.
You’ll want comfortable walking shoes because Mumbai encourages long strolls through markets, colonial spots, and those coastal promenades. Sandals work for casual outings, but I’d stick with closed shoes in crowded areas.
Don’t forget sunscreen, sunglasses, and a wide-brimmed hat—the midday sun can be relentless. A reusable water bottle is a lifesaver for staying hydrated. If you’re out after sunset, insect repellent can really help.
Planning to attend Christmas services or a festive dinner? Bring at least one modest, semi-formal outfit. Many restaurants and churches appreciate neat attire, so it’s better to skip the super casual look for those occasions.
Outdoor Activities and Weather Suitability
December’s dry, sunny weather really sets the stage for sightseeing, walking tours, and cultural events. You can easily visit attractions like Gateway of India, Marine Drive, and Elephanta Caves without battling rain or sticky humidity.
People flock to beaches like Juhu and Girgaum Chowpatty for evening strolls. The sea stays warm, hovering around 26–27°C (79–81°F), so you can swim if you want—just keep an eye on those local safety flags since currents sometimes get strong.
Christmas week lights up the city with special events, street decorations, and midnight masses at historic churches like Mount Mary Basilica and St. Thomas Cathedral. The nice weather makes it easy to bounce between outdoor celebrations and indoor gatherings.
Day trips work out well too. You can explore Sanjay Gandhi National Park or take a quick drive to nearby coastal towns. Roads usually stay dry, but holiday traffic can get heavy, so it’s smart to plan your travel times.
