New Delhi | April 7, 2025 —

The national capital is staring at a scorching summer ahead, with the India Meteorological Department (IMD) forecasting above-normal temperatures and an increase in heatwave days for the April to June period.

According to IMD’s seasonal outlook, Delhi and much of northwest India are expected to experience hotter-than-usual days and nights, with daytime temperatures likely to remain consistently above normal. Night temperatures, too, are set to rise, offering little relief even after sunset.

Heatwaves to surge in frequency and intensity

The most concerning part of the forecast is the expected rise in heatwave days across the northern plains, including Delhi. The month of April is likely to see an early spike in heatwave conditions, typically defined by prolonged periods of unusually high temperatures.

Delhiites should brace for multiple spells of extreme heat, with the IMD warning of above-average heatwave activity in adjoining regions of east and central India, which often influences weather patterns in the capital.

Rainfall: normal but not a respite

The IMD also stated that rainfall during April is likely to remain normal, offering some localized relief. Delhi and parts of northwest India could see normal to slightly above-normal rainfall, but weather experts caution that this won’t be enough to offset the overall heating trend.

What residents should do

• Avoid outdoor activity during peak heat hours (12 PM to 4 PM).
• Increase water intake and monitor hydration, especially for children, senior citizens, and outdoor workers.
• Check on vulnerable individuals and ensure fans or coolers are functional.
• Stay updated with real-time advisories from the IMD and Delhi Disaster Management Authority.

This forecast comes amid growing concerns about the impact of climate change on urban heat. Delhi recorded one of its hottest summers in recent years in 2022, and this season could set new records if the predicted patterns hold.
