It is also important to note that the arrival of the southwest monsoon in Mumbai has been delayed. It was initially predicted to arrive by May 31. However, now, forecasts suggest that it will not arrive until June 6, 2026.

The reason for this delay is chalked up to the slow transition of El Niño conditions across the Pacific. This has disrupted the early wind patterns and has subsequently delayed the arrival of the southwest Kerala monsoon in Mumbai.
