New Delhi – A dramatic shift in Delhi’s weather on Thursday evening offered much-needed relief to residents who had been reeling under a relentless heatwave. As clouds loomed over the city, a light drizzle and sudden duststorm swept through several areas, marking a refreshing change from the scorching conditions that had persisted since the start of the week.
What happened?
The India Meteorological Department (IMD) reported that the national capital experienced light rainfall, isolated thunderstorms, and gusty winds ranging between 40 and 50 kmph late Thursday. These conditions emerged as part of a broader Western Disturbance passing through the northern region of India, significantly reducing the intensity of the ongoing heatwave.

Why is this important?
This sudden weather change brought relief from the season’s first heatwave in Delhi, which had pushed mercury levels above the 40°C mark earlier in the week. Ridge and Ayanagar were among the worst-affected areas on Thursday, recording maximum temperatures of 40.9°C and 40.2°C respectively.
Where were the temperature extremes recorded?
Delhi’s primary observatory at Safdarjung logged a high of 39.6°C—4.5 degrees above normal. Similarly, Palam recorded 39.1°C and Lodhi Road matched Safdarjung’s high at 39.6°C. IMD data confirmed that Thursday night was the warmest April night in Delhi in three years, with the minimum temperature rising to 25.9°C—almost six notches above the seasonal average.

Who is affected?
Delhiites across various neighbourhoods felt the brunt of the oppressive heat earlier in the day, only to be greeted with a burst of cool air and sporadic rain showers by evening. Commuters, street vendors, and schoolchildren were seen taking refuge under trees and shop awnings as the skies darkened and the drizzle began.
When did the heatwave begin?
The season’s first heatwave in Delhi was recorded on Monday, April 7, when daytime temperatures breached the 40°C mark. The intensity peaked midweek before tapering off on Thursday evening, thanks to the brief spell of precipitation.

How is the forecast shaping up?
According to the IMD, the city can expect light to moderate rainfall and thunderstorms over the next 48 hours. Meteorologists say the presence of a Western Disturbance and a low-pressure trough will continue to influence Delhi’s weather, possibly preventing extreme temperature surges through the weekend.
Humidity levels on Thursday swung between 55% and 30%, further intensifying discomfort earlier in the day. However, the evening drizzle brought down both temperature and humidity, creating a temporary but welcome break from the heat.
