Pakistan is heading into a severe heatwave, with temperatures expected to reach 45°C in several regions over the coming days, raising concerns about public health and economic disruption.

According to the Pakistan Meteorological Department, temperatures across Sindh, southern Punjab, and interior Balochistan are likely to remain 4 to 7 degrees Celsius above normal for at least a week.

Heatwave intensifies across key regions

Meteorologists say temperatures in southern districts could reach 44°C to 45°C by the weekend, with particularly harsh conditions expected in cities like Hyderabad, Jacobabad, Dadu, and Jamshoro.

In Karachi, the temperature is forecast to range between 36°C and 38°C in the next 24 hours. However, high humidity levels of around 66% are expected to make conditions feel significantly hotter.

Central and southern Punjab are also likely to experience heatwave-like conditions, while northern areas may see occasional dust storms and isolated rainfall offering temporary relief.

No immediate rain relief

Weather experts warn that no significant rainfall is expected in the near future, meaning the heat spell could persist.

They attribute the early May spike in temperatures to broader climate patterns, cautioning that prolonged dry conditions may intensify the impact.

Emergency measures and advisories

Chief Minister Murad Ali Shah has placed authorities on high alert, directing the immediate establishment of heatwave relief camps in vulnerable districts.

Hospitals have been instructed to ensure emergency preparedness, while citizens have been urged to take precautionary measures.

Officials have advised avoiding direct sunlight between 11 am and 4 pm, staying hydrated, and covering the head when outdoors. Special caution has been recommended for children, the elderly, and outdoor workers to prevent heatstroke.

Despite light sea breezes in Karachi providing limited relief during mornings and evenings, experts warn that intense sunlight and dry daytime conditions will keep temperatures dangerously high.

With the heatwave tightening its grip, authorities say the coming days will be critical in managing both health risks and infrastructure strain across affected regions.
