Kolkata Records 28% Surplus Monsoon Rain Despite El Nino
IN · Published Oct 1, 2026
• Kolkata has experienced an exceptional monsoon season in 2026, recording 1,718.9mm of rainfall between June and September, which is 28% above the climatological average of 1,345.5mm for the period.
• This surplus comes despite the presence of El Nino, a phenomenon typically associated with reduced monsoon activity in India.

Impact & Risks

The surplus rainfall has positively impacted Kolkata and surrounding areas, ensuring adequate water resources and supporting agricultural activities. However, heavy rains earlier in the season may have caused localised flooding and waterlogging in urban areas. With the monsoon nearing its withdrawal, risks of further heavy rainfall appear minimal, although isolated showers may still occur.
