Honestly, if you stepped outside in Mumbai today, January 18, 2026, you probably noticed that the air feels a bit "heavy." Not in a rainy way—since the chance of precipitation is a flat 0%—but there’s a specific kind of coastal thickness that makes the actual 76°F current temperature feel a lot different than it looks on paper.
Mumbai is currently sitting under clear night skies, but "clear" is a relative term in the Maximum City. While the thermometer reads 76°F, the humidity is holding steady at 60%. That’s the classic Mumbai trap. It’s technically winter, but the Northwest winds blowing at 10 mph are doing more to move the haze around than they are to actually cool you down.
What the temperature of today in mumbai really means for your day
We’ve had a high of 80°F today. It’s not scorching, but it’s definitely warm enough to make a commute feel like a marathon if you’re stuck in traffic on the Western Express Highway. The low for tonight is expected to dip to 71°F. For anyone living in Delhi right now—where they’re shivering at 5.3°C (41.5°F)—that sounds like a tropical vacation. But for a Mumbaikar? That 71°F is just enough to justify pulling out a light hoodie that has stayed in the back of the closet for eleven months.
The UV index earlier reached a 6, which is categorized as "high." If you were out at Marine Drive around noon, the sun was definitely biting.

Why the humidity is the real story
Humidity at 60% to 62% might not sound extreme compared to the monsoon months when it hits 90%, but in January, it changes the "feels like" temperature significantly. Basically, your body can't sweat as efficiently. Even though it’s 80°F, your skin probably feels like it's closer to 84°F.
- Current Temp: 76°F
- Daytime High: 80°F
- Nighttime Low: 71°F
- Humidity: 60%
- Wind: 10-12 mph from the Northwest
The air quality is also playing a role in how the temperature "feels." Today's AQI in Mumbai has been hovering around 176, which is firmly in the "Unhealthy" zone. When the air is this thick with particulate matter, it can trap heat closer to the ground, a phenomenon often discussed by local meteorologists when explaining why urban heat islands like Dadar or Andheri feel five degrees warmer than Colaba.
Is this normal for a Mumbai January?
Usually, January is the month we all wait for. It’s supposed to be the "pink cold" (gulabi thandi). Historically, the average high for this time of year is closer to 86°F, so today’s 80°F is actually on the cooler side of the average. You’ve basically caught Mumbai on a "good" day, even if the mist this morning made the visibility drop to about 2.5 km.

What’s interesting is the wind direction. We’re seeing consistent Northwest winds. These are coming off the sea, which usually helps regulate the heat, but they also bring in that moisture. If the wind were coming from the North (land-ward), we’d be seeing those crisp, dry mornings that make the city feel like a different planet.
Survival tips for the current Mumbai weather
If you’re planning your Monday based on today’s patterns, expect more of the same. The forecast for tomorrow shows another high of 79°F.
- Hydrate more than you think. Even at 76°F, the 60% humidity is draining.
- Mask up for more than just health. With an AQI of 176, your lungs will thank you, and it actually helps keep your face from feeling that grimy "city film" that happens when humidity meets pollution.
- Cotton is your best friend. Forget the synthetics. Even though it’s "winter," the afternoon sun at a UV index of 6 will turn a polyester shirt into a personal sauna.
The real shift is coming later in the week. We’re looking at a gradual climb toward 81°F and 82°F by Wednesday. So, if you were planning a long walk at Shivaji Park or a trip to Elephanta, tonight and tomorrow morning are your best windows before the heat starts to crank back up.

Keep an eye on the wind speed. If it drops below 10 mph, the air will stagnate, and that "Unhealthy" AQI will likely climb. For now, enjoy the 71°F night—it’s about as "chilly" as this city gets before the inevitable March swelter kicks in.
Actionable Insight: Check the AQI levels before your morning run tomorrow; if it stays above 170, consider an indoor workout. Wear light, breathable layers for the morning commute to handle the 9-degree swing between the early morning low and the afternoon peak.
