Sat Jan 31 18:44:59 UTC 2026: # Tamil Nadu Experiences January Rainfall Surplus and Chilly Weather

The Story:

Tamil Nadu concluded January 2026 with a rainfall surplus due to multiple rain spells and a delayed withdrawal of the Northeast monsoon. The Regional Meteorological Centre (RMC) forecasts continued light rainfall in coastal and Western Ghats districts until February 6, 2026, attributed to an upper-air cyclonic circulation over the Bay of Bengal. While northern districts might experience fog, Erode, Namakkal, and Karur could see mist. Despite near-normal official temperature readings, residents experienced chilly weather due to direct exposure, with Nungambakkam and Meenambakkam recording temperatures below 20 degrees Celsius on multiple days.

Key Points:

  • Tamil Nadu recorded 33.1 mm of rainfall in January against a monthly average of 12.2 mm.
  • The RMC forecasts light rainfall in coastal and Western Ghats districts until February 6, 2026.
