Details & Context
According to the latest updates from the @IndiaMeteorologicalDepartment (IMD) shared via posts on X and regional weather reports, South Bengal is grappling with oppressive heat and humidity. Kolkata recorded a daytime high of 35.2°C and a night time low of 28.8°C with humidity levels soaring to 100% by afternoon. Districts like West Bardhaman, West Medinipur and Birbhum are under heatwave alerts until Thursday. However, a dramatic shift is expected as the southwest monsoon which entered the Nicobar Islands five days early on May 13th, 2025 advances into the Bay of Bengal and Andaman Sea. By May 17th, it’s likely to reach central Bay of Bengal and the Andaman Islands, bringing relief to parched regions.

Quotes

·      “The early monsoon arrival in Nicobar is a game-changer. South Bengal will see relief from the heat soon but storms are coming first,” said a senior @IMD official on X.

·      “Kolkata is suffocating with humidity at 100%. Light rain might hit by evening but real relief is expected Thursday,” shared a local weather enthusiast on social media.

Additional Information
The IMD’s data, cross-referenced with X posts, highlights the monsoon’s rapid progression. On May 14th, it covered parts of the south Bay of Bengal, south Andaman Sea and north Andaman Sea. Favourable conditions suggest it will advance further within 72 hours. In Kolkata, humidity levels fluctuated from 48% at dawn to 85% by midday making conditions unbearable. Light rain is possible in some areas by Wednesday evening but significant rainfall is expected Thursday and Friday. North Bengal’s heavy rain warnings are critical, as 200 mm of rain could trigger flash floods in low-lying areas.
