Historical comparison
Monsoon history in Mumbai
This year's delayed monsoon is a stark contrast to last year's early arrival on May 26. In previous years, like 2019 and 2023, the monsoon was also delayed till June 25. Another major delayed onset was recorded in 2009 when it arrived on June 21. This year has been especially unusual due to El Niño conditions, which have kept city reservoirs critically low.
