“We can expect rain in the hills too on May 29, with rain activity likely across the plains till May 30 and even 31,” he said.

IMD forecasts no heatwave conditions in Delhi until at least June 3. While the maximum may dip to around 34°C by Saturday, a gradual rise to 39-41°C is likely by June 3. The minimum is likely to hover between 23-25°C on Friday. Typically, monsoon rains hit Delhi by June 27.
