Kolkata weather today: Cloudy skies, light rain likely as September showers linger

Kolkata is likely to begin Saturday, September 26, under generally cloudy skies, with light rain expected at intervals as the city continues to experience a lingering spell of monsoon-influenced weather. The latest forecast from the India Meteorological Department (IMD) indicates that temperatures in Kolkata are likely to remain in the range of 27°C to 33°C, with the possibility of light rain during the day. No specific warning has been issued for Kolkata for Saturday. ⁠

The weather is expected to remain humid despite the relatively moderate temperatures. The city’s recent weather pattern has been marked by frequent cloud cover and intermittent showers rather than prolonged spells of heavy rain. At Kolkata-Dum Dum, the IMD recorded a minimum temperature of 26.5°C on September 25, while the station received 32.7 mm of rainfall in the preceding 24-hour period. Relative humidity at 8.30am was recorded at 85%, highlighting the moisture-laden conditions over the city and its surroundings. ⁠

The Kolkata-Howrah weather station also recorded rainfall during the same period, with 11 mm of rain reported in the 24 hours ending at 8.30am on September 25. The minimum temperature there was 24.5°C, while morning relative humidity stood at 83%. These readings indicate that rain activity has remained significant across different parts of the metropolitan region, although the intensity can vary considerably from one locality to another. ⁠

The Regional Meteorological Centre’s observations also show that rainfall was recorded across several parts of West Bengal on September 25. At Alipore, Kolkata received 36.7 mm of rain, while Dum Dum recorded 32.7 mm. Salt Lake recorded 32.3 mm. The rainfall was accompanied by comparatively cooler daytime conditions in several parts of the state, with Alipore recording a maximum of 30.6°C and Dum Dum 31.7°C in the latest available observations. ⁠

For Kolkata residents, Saturday is therefore likely to feel more like a typical late-monsoon day than the beginning of a sustained transition towards dry autumn weather. Cloud cover should keep the sun from becoming too harsh for much of the day, although humidity may continue to make the atmosphere feel warmer than the thermometer suggests. Short spells of rain could also lead to temporarily wet roads and slower traffic in parts of the city, particularly if showers coincide with peak commuting hours.

The forecast also suggests that the change in weather will be gradual rather than abrupt. IMD’s seven-day outlook keeps generally cloudy conditions and the possibility of light rain in the forecast for Kolkata through September 29, while temperatures are expected to rise somewhat, with daytime maximums reaching around 34°C. By September 30, the forecast shifts towards generally cloudy conditions without a specific rain indication. ⁠

The pattern reflects the transitional character of late September in Kolkata. The city is approaching the end of the traditional southwest monsoon season, but moisture and occasional rain-producing systems can still influence weather over south Bengal. As a result, residents may continue to see a mix of cloudy skies, humid afternoons and sudden showers even as temperatures gradually begin to climb again.

For those stepping out on Saturday, keeping an umbrella handy would be sensible, particularly because the forecast does not rule out light rain during the day. Commuters may also want to allow some additional travel time if showers become locally intense, as rainfall can quickly affect traffic movement on Kolkata’s busy roads.

Overall, Saturday’s weather is expected to remain cloudy, humid and occasionally wet, with no major weather warning currently indicated for Kolkata. The bigger change may come in the following days, when temperatures are forecast to edge upwards towards the mid-30s while the possibility of occasional rain gradually decreases. ⁠
