Birbhum’s Labpur recorded the highest rainfall at 44.2 mm, followed by Jhargram (23.2 mm), Bankura (22.8 mm), and Manteswar in Purba Bardhaman (22.2 mm). This weather pattern is influenced by the Indian Ocean Dipole (IOD) and the El Niño-Southern Oscillation (ENSO).

  • The India Meteorological Department (IMD) has predicted a week of active pre-monsoon weather, dominated by rainfall and thunderstorms rather than heatwave conditions.
  • The National Disaster Management Authority (NDMA) has advised fishermen along the coast not to venture into the sea till May 5 due to squally winds reaching 40-60 kmph.
  • The Ministry of Earth Sciences has been monitoring the weather patterns and has predicted that the temperatures in North Bengal will remain stable, with no major rise in daytime temperatures expected during the next seven days.

Significance of Weather Patterns in West Bengal

The weather patterns in West Bengal have significant implications for the state's agriculture, economy, and daily life.
