Mumbai Braces for Sunny Winter Day with Air Quality Warning
Mumbai residents can expect a bright and easygoing winter day on Monday, January 19, 2026. The city will bask in sunny skies with comfortable temperatures warming up to around 26°C. This pleasant weather creates ideal conditions for daily activities and evening plans.
Today's Detailed Weather Forecast
The day begins with a mild start near 21.4°C before temperatures climb to approximately 26°C. The average temperature for Monday is projected to be around 23.7°C. Humidity levels will sit at about 55%, making the coastal air noticeable by midday without feeling sticky.
Forecasters predict zero millimeters of rain with absolutely no chance of precipitation. Winds may pick up to about 18.4 km/h, providing a gentle coastal breeze that tempers the afternoon sun. Visibility should remain near 10 kilometers, which is generally good for the city.
Around sunset at 6:23 PM, temperatures will ease down and the breeze will become more noticeable. This creates a perfect window for outdoor workouts or relaxed seaside strolls along Mumbai's famous coastline.
Air Quality Concerns Linger from Sunday
Despite the pleasant weather conditions, Mumbai faces significant air quality challenges. On Sunday, January 18, the city recorded air quality that fell into the poor category. The Air Quality Index for India registered at 137, while the corresponding US measurement reached 157.
Particulate matter levels remain particularly concerning. PM2.5 levels were recorded at 70, and PM10 levels reached 87. Both measurements are high enough to potentially irritate throats and eyes. They could also trigger symptoms for individuals with asthma, allergies, or other breathing conditions.
Carbon Monoxide levels measured 326, contributing to the overall pollution load, especially in areas prone to traffic congestion. Sunny, dry weather does not automatically clear pollution in the same way rain can, allowing yesterday's poor air quality to linger into Monday morning.
Recommendations for Residents
For those stepping out early, the morning offers pleasant walking conditions but also requires precautions. Light-to-moderate winds should improve pollutant dispersion through the afternoon, but mornings can still feel stuffy in dense neighborhoods and along major traffic corridors.
- Keep activities flexible during the first half of the day if you experienced discomfort yesterday
- Carry a mask for stretches with heavy traffic, especially for two-wheeler riders
- Plan longer walks or runs for late afternoon into early evening when the breeze improves
- Individuals sensitive to pollution should avoid congested stretches during peak office hours
- Carry sunglasses, use light sunscreen, and keep water handy during lunchtime outings
Week Ahead Weather Outlook
Mumbai's weather outlook remains consistently bright for the upcoming week. Sunny conditions are expected to prevail right through January 25 with no rain signals present in the forecast.
Daytime highs will hover in the mid-20s for most of the week:
- January 20: High of 25.2°C
