Despite the spike, no station met the heatwave criteria, similar to conditions on Sunday. However, after a scorching day, weather conditions shifted by evening, with a dust storm sweeping across the capital between 8 pm and 9 pm. Around 7 pm, the IMD issued an alert warning of gusty winds and possible light rain, though no rainfall was recorded till late Monday. An IMD official said wind speeds peaked at 61km/hour at Pragati Maidan, followed by 54km/hour at Pusa.

A yellow alert has been issued for Wednesday, with one to two spells of light rain and gusty winds of up to 50km/hour expected, likely bringing the maximum temperature below the 40°C mark. “Temperatures are likely to dip from Tuesday, with chances of drizzle to very light rain on Tuesday and light rain on Wednesday. The maximum should return close to normal and even below normal by Thursday,” an IMD official said.

The city had recorded heatwave conditions for three consecutive days between Thursday and Saturday. While isolated heatwave conditions were observed in pockets on Thursday and Friday, a citywide heatwave was declared on Saturday — the hottest day of the year so far — when the Ridge station recorded 44.5°C and Safdarjung touched 42.8°C.

No station met this criteria on Monday, similar to Sunday. On Saturday, four stations were meeting this criteria; two on Friday and one on Thursday. Mahesh Palawat, vice-president at Skymet, said the expected rain is likely due to a cyclonic circulation over central Pakistan and adjoining northwest Rajasthan. “On Monday, we already saw some rain in Rajasthan and it will move to Delhi, via Haryana, by Tuesday. More rain is likely on Wednesday and remnants of this spell are likely on Thursday too. In addition to the cyclonic circulation, some moisture is also being fed by the Arabian Sea and the rain will lead to temperatures dipping below 40°C again,” he said, adding that there is a possibility of some more pre-monsoon showers on May 5 as well. Heatwaves in April are not uncommon in Delhi. The city recorded three such days between April 7 and 9 last year. In April 2022, there were as many as 11 heatwave days, while April 2017 saw four and April 2016 recorded one. The IMD declares a citywide heatwave only when Safdarjung is among at least two stations meeting the criteria.
