NEW DELHI: The city recorded its hottest April night in six years on Sunday, with the minimum temperature settling at 27.2°C — three degrees above normal and the highest this year so far. The temperature jumped by about 7°C since Saturday, when the maximum reached 42.1°C, the hottest day of the season.

"We experienced extreme surface heating on Saturday, which resulted in a high maximum temperature. With cloudy skies at night, however, this surface heat did not escape sufficiently at night," explained Mahesh Palawat, vice president at Skymet.
The IMD predicts a marginal dip in temperatures with gusty winds and light rain by Tuesday. "A fresh western disturbance is likely to affect the western Himalayan region from May 2, 2025," the IMD stated.

IMD has predicted for Tuesday light rain or drizzle, thunderstorms, and surface winds reaching 30–40 km/hr, gusting up to 50 km/hr. Rain is also expected on May 2 and 3 under the influence of the western disturbance.
The maximum temperature is forecast to be 40–42°C on Monday, dipping slightly to 38–40°C on Tuesday. The minimum will hover between 25 and 27°C.
