The Pakistan Meteorological Department warned of an impending heatwave and extreme weather shifts across large parts of Pakistan [1, 2].
These forecasts signal a significant risk to public health and agriculture in southern Pakistan, where temperatures often reach critical levels during the pre-monsoon season.
The PMD released the warning on April 28, 2026 [1]. The agency said that heat conditions were expected to intensify throughout May 2026 [1]. According to the department, the possible development of an El Niño phenomenon in May could be the primary driver for these shifts, a process that often intensifies heat and alters established weather patterns [1].
While the initial warning focused on extreme heat, subsequent forecasts showed a shift in weather volatility. Reports from May 1, 2026, indicated that the PMD also forecast heavy rain, hailstorms, and strong winds in various parts of the country starting May 2 [1].
Southern Pakistan remains the area of highest concern for the heatwave. The combination of potential El Niño effects and seasonal shifts creates a volatile environment for the region [1, 2]. The PMD said it continues to monitor these atmospheric changes to provide updated alerts to the public [2].
“The PMD warned of an impending heatwave and extreme weather shifts across large parts of Pakistan.”
The intersection of a potential El Niño event with seasonal heatwaves suggests a period of high climatic instability for Pakistan. When heatwaves are followed by sudden heavy rains and hailstorms, it increases the risk of flash flooding and crop failure, complicating the country's food security and disaster management efforts.
