Weather Kolkata: Thunderstorms and Temperature Drops Expected

Who is involved

Weather conditions in Kolkata have recently shifted dramatically, contrasting sharply with prior expectations. Before March 17, 2026, the forecast for Kolkata indicated a typical warm March, with temperatures hovering around 23°C. Residents and businesses were preparing for a season characterized by mild weather, with little indication of the tumultuous conditions that would soon unfold.

However, a decisive change occurred on March 17, when the India Meteorological Department issued a yellow alert for Kolkata and several districts across West Bengal. This alert signaled the onset of scattered thunderstorms, which are expected to persist across Kolkata and South Bengal until March 22, 2026. The immediate impact of this alert was felt as wind speeds began to rise, ranging between 30 and 50 kmph during thunderstorms, and temperatures dropped from around 23°C to nearly 17°C due to the rain.

The direct effects of this weather shift have been significant for the local population. On March 17, the maximum temperature in Kolkata was forecasted to reach around 33°C, with a minimum of 24°C. However, the sudden drop in temperature has prompted many residents to adjust their daily routines, with some opting for warmer clothing and others altering their outdoor plans. Additionally, light rain and thundershowers were predicted at isolated places in several districts, including North and South 24 Parganas, Nadia, and Murshidabad, further complicating daily life.

As the thunderstorms continue, the potential for severe weather remains a concern. Thunderstorms with lightning and gusty winds of 30–40 kmph are expected on March 20, 2026, adding to the unpredictability of the current weather situation. Rainfall activity is anticipated to increase again from March 19, which could lead to further disruptions. Reports from local tea estates indicate significant rainfall, with the highest recorded at Sankos Tea Estate in Alipurduar, measuring 16 cm, while Kumargram Tea Estate received 13 cm, and Newlands Tea Garden and Bhutanghat recorded 12 cm.

Experts emphasize that such weather patterns are not uncommon for this time of year in Kolkata. The region often experiences thunderstorms and rainfall as part of its seasonal climate. However, the intensity and frequency of these storms can vary significantly, impacting agriculture, transportation, and daily life. The current situation serves as a reminder of the unpredictable nature of weather in the region.

As Kolkata braces for the continuation of these weather patterns, residents are advised to stay informed through official channels. The India Meteorological Department continues to monitor the situation closely, providing updates as necessary. While the immediate effects are being felt, the long-term implications of this weather shift will depend on how the storms evolve over the coming days.

Overall, the weather in Kolkata is undergoing a notable transformation, with thunderstorms and a significant drop in temperatures reshaping the expectations for the coming week. As the city navigates these changes, the resilience of its residents will be tested, and the importance of preparedness will be underscored in the face of nature’s unpredictability.
