Kolkata Weather Today: Rain, Thunderstorms Likely; Cloudy Skies Set to Dominate City on September 8

Kolkata is likely to remain under the influence of an unsettled monsoon pattern on Tuesday, September 8, with cloudy skies, rain and thunderstorms expected to keep the weather conditions volatile across the city. The latest India Meteorological Department (IMD) forecast indicates that Kolkata and adjoining areas could see spells of moderate rain, with thunderstorms accompanied by lightning and gusty winds also possible. ⁠

According to the latest Kolkata-Alipore forecast, the minimum temperature is expected to remain around 26°C, while the maximum could settle near 31°C. The relatively modest daytime temperature, however, may not translate into comfortable conditions as high humidity is likely to continue adding to the city’s familiar monsoon discomfort. The Alipore observatory recorded a minimum of 28.7°C on September 7, with morning relative humidity at 86 per cent and evening humidity at 90 per cent. ⁠

The bigger weather story for Kolkata today is the possibility of rain accompanied by atmospheric instability. The IMD’s city forecast describes the day as generally cloudy with moderate rain and warns of thunderstorms with lightning and gusty winds reaching around 30–40 kmph. This means that even where rainfall is not continuous, sudden showers could develop and intensify over short periods. ⁠

For commuters, the weather could therefore prove particularly unpredictable. A relatively quiet morning may quickly give way to a sharp spell of rain or thunderstorm activity later in the day. Waterlogging in vulnerable stretches, slower traffic and temporary disruption to outdoor activity cannot be ruled out if heavier showers develop over the metropolitan area.

The latest broader weather reports also point towards continued intense monsoon activity over West Bengal. A fresh forecast published today says several parts of the state could experience heavy to very heavy rainfall, with thunderstorms and strong winds remaining a concern. ⁠

Kolkata’s unsettled spell is unlikely to disappear immediately. The IMD’s extended city forecast keeps moderate rain and thunderstorm activity in the picture for September 9 as well, with a further thunderstorm-and-rain possibility on September 10. Conditions are then expected to gradually become less intense, although cloudy skies and occasional light rain may continue through the following days. ⁠

The neighbouring Howrah forecast similarly indicates a wet and unstable Tuesday, with a few spells of rain or thundershowers and the possibility of heavy rainfall accompanied by thunderstorms and gusty winds. This suggests that the weather disturbance is not likely to remain confined to isolated pockets of Kolkata but could affect the wider urban belt as well. ⁠

For residents, the practical message is straightforward: Tuesday is not a day to assume that a cloudy morning means a rain-free afternoon. Those heading out should keep rain protection handy, while motorists need to exercise additional caution during sudden downpours, particularly when visibility drops or roads become waterlogged. During thunderstorms, people should also avoid exposed locations and unnecessary travel through open areas.

With temperatures staying comparatively restrained but humidity remaining high, Kolkata is likely to experience a distinctly monsoon-heavy day rather than a return of clear, dry conditions. The combination of thick cloud cover, intermittent rainfall, lightning and gusty winds could give the city a grey and occasionally turbulent September Tuesday.

Kolkata’s weather today is expected to remain cloudy, humid and rain-prone, with thunderstorms and gusty winds adding to the weather risk. The forecast suggests that the monsoon remains firmly in control of the city’s skies, and residents should be prepared for sudden changes in conditions through the day.
