The Indian Meteorological Department (IMD) has forecast above-normal heatwave days for May 2026 as temperatures soar across the country [2].

This extreme weather threatens public health and infrastructure across northern, eastern, and central India. The persistence of high temperatures increases the risk of heat-related illnesses and puts pressure on the national power grid during peak demand.

Temperatures in several Indian cities have risen to between 45°C and 48°C [1]. The intense heat is particularly severe in Delhi, Gujarat, and Maharashtra, where the IMD has issued weather alerts [1].

Officials said the current conditions are due to climate-change-driven warming [2]. This trend is leading to an increased frequency of heatwave days and notably warmer nights, which prevents the environment and human bodies from cooling down effectively [2].

Recent weather patterns have shown some volatility. While the IMD predicts a month of extreme heat, some regions experienced rain and thunderstorms over the past week that brought temperatures down and offered temporary relief from the heat [1].

Despite these brief interruptions, the broader forecast for May 2026 remains critical [2]. The IMD continues to monitor the northern and central regions as the heatwave persists through the month.

The convergence of record-high daytime temperatures and warming night-time minimums indicates a shift in India's seasonal climate patterns. When nights remain warm, the cumulative heat stress on the population increases, potentially offsetting the relief provided by sporadic thunderstorms and intensifying the long-term impact of global warming on the subcontinent.
