Seasonal Shift: Monsoon Withdrawal and Heat Wave Monitoring

The withdrawal of the Southwest Monsoon is a gradual process that typically starts in the northwest. According to an IMD press release dated September 18, 2026, the process is expected to commence in parts of West Rajasthan around September 19, 2026. This shift often leads to a change in humidity levels and the onset of clearer skies in the north, though the transition can be volatile.

Simultaneously, the IMD is maintaining a focus on extreme temperature patterns. The department is currently conducting a Heat Wave Alert Survey, which runs from August 13 to September 20, 2026, to better understand and predict temperature spikes during these transitional periods.

What This Means for Residents

• North and Central India: Expect misty mornings and a gradual decrease in rainfall as the monsoon retreats.
• South India: Cities like Chennai continue to see active weather with thunderstorms, indicating that the monsoon's influence remains strong in the south.
• Planning: With high humidity (reaching 97% in Kolkata) and varying visibility due to fog/mist in several metros, commuters should stay updated on real-time alerts via the IMD official portal.
