An intense heatwave has gripped Delhi and the National Capital Region, with daytime temperatures reaching as high as 45°C [1].

These extreme conditions threaten public health and infrastructure in one of the world's most populous urban areas. The severity of the heat puts significant strain on the city's power grid and water supplies during the peak of the season.

Reports from April 25, 2026, indicate that temperatures across large parts of the region hovered between 43°C and 45°C [1]. Other data from the same date recorded a maximum temperature of 41.9°C [2]. This figure represented a 0.2°C increase over the previous day [2].

Meteorological data shows the heat is significantly above seasonal norms. On April 25, 2026, the temperature was 4.2°C above the normal average for that time of year [2].

Experts said the current weather pattern is due to a persistent high-pressure system [1]. This system has prevented cooling relief from reaching the region, effectively trapping heat over the city and its surrounding suburbs.

The heatwave affects residents throughout Delhi and the broader NCR area in northern India [1, 2]. While some parts of North India may find relief soon, the region continues to struggle with the unusually high heat conditions [2].

“Temperatures across large parts of Delhi-NCR hovered between 43°C and 45°C.”

The occurrence of temperatures significantly above the seasonal norm in late April suggests an acceleration of extreme weather patterns in northern India. When high-pressure systems stall over urban heat islands like Delhi, the lack of ventilation increases the risk of heatstroke and systemic urban failure, highlighting the region's vulnerability to climate volatility.
