Key Takeaways:

  • Mumbai has remained hot and humid due to persistent westerly winds and the absence of pre-monsoon showers.
  • The city crossed 35°C on six occasions this May, unusual for coastal weather conditions.
  • Light pre-monsoon showers are likely between 28 and 31 May across Mumbai and suburbs.
  • Better rainfall activity and some relief from humidity are expected during the beginning of June.

While there are unconfirmed whispers of monsoon being round the corner in Kerala, Mumbai continues to reel under hot and sultry conditions. The city has not observed any pre-monsoon showers so far during the last one month. Mumbai normally does not witness any heat wave conditions in May, and the temperature remains within the bounds of 35°C, +/- 1°C. The capital city has breached the 35°C mark on 6 days during this month, and the highest maximum was logged at 35.8°C on 11 May 2026. There is hardly any land breeze setting in during late evening/night hours. Uninterrupted prevalence of westerly winds from the sea has kept the humidity levels rather high, both during day and night.

There is a feeble weather system as cyclonic circulation over the central and southeast Arabian Sea. Also, there is likelihood of another system coming up over the far eastern side of Bay of Bengal shortly. A western disturbance and its induced circulation will bring change in the wind stream over the plains of North India. All these potential weather systems will change the wind flow characteristics along the Konkan Coast. The combined effect may trigger the first pre-monsoon showers over the city and suburbs.

Very light rainfall along with partly cloudy sky is likely on 28th & 29th May 2026. As the likely system forming over Bay of Bengal shifts to the central parts of the sea, the wind stream strengthens along the Konkan Coast. The fleeting showers may become little more frequent on 30th & 31st May. The intensity of rain will remain mild and therefore may not provide any significant relief from the muggy weather. Yes, the month of June may start with some moderate showers, promising relief from the raging heat and humidity.
