Kolkata Weather Today: Cloudy Skies, Rain and Thunderstorms Likely as Monsoon Keeps City on Alert

Kolkata is likely to remain under a predominantly cloudy sky on Sunday, September 6, with the monsoon continuing to keep weather conditions unsettled across the city. The latest forecast from the India Meteorological Department (IMD) indicates that Kolkata can expect light rain during the day, while other weather forecasts point to the possibility of a thunderstorm in some areas, particularly during the afternoon. ⁠

The IMD’s Kolkata-Howrah forecast puts today’s temperature range at around 28°C to 35°C, with generally cloudy conditions and the possibility of light rain. This suggests that although the cloud cover may provide some relief from direct sunshine, the city could still feel warm and humid as the day progresses. ⁠

The weather comes after another spell of unsettled conditions in Kolkata on Saturday. Parts of the city experienced rain accompanied by lightning and gusty winds, with winds reaching around 40 kmph in parts of north Kolkata, according to reports. ⁠

The combination of persistent moisture, cloud cover and intermittent rainfall is expected to keep the atmosphere uncomfortable at times. Even when rainfall remains light, high humidity can make temperatures feel considerably warmer than the actual reading. Residents stepping out during the day may therefore experience a sticky and humid afternoon, particularly during breaks in rainfall.

The current weather pattern also highlights the continuing influence of monsoonal activity over southern West Bengal. Recent reports have linked the unsettled conditions over Kolkata and neighbouring districts to an active monsoon trough and atmospheric circulation, with several parts of South Bengal witnessing spells of rain. ⁠

For Kolkata, however, today’s forecast does not indicate a major severe-weather warning. The IMD’s city forecast currently describes the day as generally cloudy with light rain, while the more detailed forecast shows no specific warning for September 6. The situation is expected to become more active again on September 7, when thunderstorms accompanied by lightning and gusty winds of around 30–40 kmph are forecast. ⁠

The wet spell is unlikely to disappear immediately. The IMD’s extended city forecast indicates generally cloudy conditions with rain or thundershowers on several days through the coming week. September 8 and 9 could see one or two spells of rain or thundershowers, while another spell of thunderstorm activity is possible later in the week. ⁠

For commuters, Sunday could therefore bring the familiar monsoon challenge of sudden showers rather than continuous heavy rain. Roads may become slippery during downpours, while temporary waterlogging could affect low-lying stretches if rainfall intensifies over a short period. Those travelling by two-wheelers should remain particularly cautious during thunderstorms and avoid exposed locations when lightning becomes frequent.

The cloudy conditions may also keep Kolkata’s temperature from rising sharply at certain times, but humidity will remain the bigger discomfort factor. Residents should remain prepared for quick changes in weather, especially if dark clouds gather during the afternoon.

With the monsoon still active and more rain-bearing systems influencing eastern India, Kolkata’s weather is expected to retain its unpredictable character in the coming days. For Sunday, the broad message is clear: keep the umbrella handy, expect a largely cloudy sky, and be prepared for a spell of rain or thunderstorm rather than assuming the day will remain dry. ⁠
