Mumbai's weather department has put out a yellow alert, signaling be ready for changing conditions like cooler nights and possible light showers. This comes as the city sees ups and downs in temperature after New Year's rains. No heavy downpours expected, but folks should watch for fog and chilly evenings.
Yellow Alert Meaning Mumbai
An IMD yellow alert means a weather change could happen soon and should be of caution to those receiving it. This could involve, but not limited to: light rainfall, strong winds, fog, and some other, lesser forms of weather. It does not signal anything too severe, but merely suggests people prepare for it while being on safety's side.
The colours of the weather alerts will be green, which means "everything is fine", yellow which means "be alert for what could happen", orange means "be prepared" and red would indicate "shelter will be necessary". In Mumbai it is quite typical for these alerts to originate from periods of seasonal change (ie, winter – when there is water vapour in the air). An example that has created awareness in Mumbai is that of local residents who have experienced these cooler temperatures previously during periods of change.
Current Mumbai Weather Status
As of January 3rd, 2026, there will be cloudy skies and daytime temperatures will range from 29 degrees Celsius down as low as 16-19 degree Celsius during the Evening. The air quality improved since the drizzle occurred and is now at an air quality index of 122. There does not appear to be more large-scale rainfall expected at this time, however morning drivers may encounter fog hanging about.
The India Meteorological Department (IMD) continues to closely monitor the Konkan region, including Thane and Palghar, with average wind speeds of 20 km/h and humidity levels of about 50-70 per cent. This weather pattern follows a period of "unseasonal" New Year's Eve precipitation which took everyone by surprise.
Impacts on Mumbai Daily Life
There may be decreased moving traffic if extremely. Fog will make traffic slow down on main highways such as the eastern express. Schools and other offices won't close down, considering conditions are not terrible yet. Parents will need to verify what route their children will take home. An adequate amount of moisture remains on the road, which creates potential slip hazards for those commuting.
The fisherman has been warned to stay close to shore due to frequent periods of rough surf. Jogging on the beaches or visiting outdoor markets located in various parks along Marine Drive will require you to dress in layers because it could get very chilly. There is nothing to worry about in regards to losing electricity; that kind of event does not happen with such frequency or intensity as larger storms do.
Safety Tips During Yellow Alert
Keep a jacket and water handy, for temperature decreases, as you travel. Go slow and use your fog lights while you drive. Follow what other people are doing in your area with live traffic applications. Ensure that your phones have enough charged battery to receive IMD alerts via mobile app or text message.
Keep some 'easy to eat' snack items in your home because some stores may close early (including grocery stores). Older adults and children should remain indoors during very windy conditions. Drink fluids (as well as take in nutrition) to combat the drying effect of cool and low humidity conditions as well.
Mumbai Weather Forecast Next Days
January 4-7 looks dry mostly, with sunny spells and gradual warming by 2-3°C. Light showers chance fades after today. Check IMD site daily for tweaks.
Winter here means less rain overall, under 2 wet days a month normally. But climate shifts bring surprises, so track patterns.
Why Yellow Alerts Happen in Winter
Cold Fronts from North India combine with Moisture-laden Air from the Arabian Sea near Mumbai; occasionally also stirred up by Disturbances from Far Sea Cycles to Generate Low-Pressure Conditions Leading to Fog/Lag Drips. The occurrence of fog and drip production from Mumbai has increased during the Last 10 Years, due largely to Jet Stream Alterations via Global Warming. It has been suggested that tracking sea-surface temperatures in Future will be Helpful in Forecasting Future Conditions More Accurately.
