Pakistan is in the grip of an unprecedented heatwave, with temperatures nearing 50°C in several cities, raising public health concerns and prompting emergency responses across provinces.
According to the Pakistan Meteorological Department (PMD), the highest temperature recorded on Thursday was 47.7°C in Jacobabad, while Lahore sizzled at 43°C and Karachi at 38°C with high humidity levels. The PMD has issued a red alert for Sindh and Punjab, warning of continued extreme weather until at least May 25.
“This is one of the most prolonged and intense heatwaves we’ve seen in recent years,” said Dr. Fayyaz Bilal, a senior meteorologist. “The combination of high temperature and humidity makes this extremely dangerous, especially for children, the elderly, and outdoor workers.”
Health departments across provinces have reported a surge in cases of heatstroke and dehydration. Hospitals in major cities are on high alert with emergency cooling centers being set up in government buildings and community halls.
The Punjab government announced early summer vacations in all public and private schools starting immediately, citing student safety. Educational institutions in Sindh are also expected to follow suit.
The National Disaster Management Authority (NDMA) has launched a public awareness campaign advising citizens to stay indoors, hydrate frequently, and avoid peak afternoon hours. Labor unions are urging employers to reduce working hours for outdoor staff.
Climate experts warn that rising temperatures are a sign of a growing climate crisis. “South Asia is now facing climate extremes as the new normal. Without urgent climate action, these events will grow more deadly each year,” said Dr. Mahreen Shah, an environmental policy researcher.
Meanwhile, power grids in urban centers are under strain as air conditioner and fan usage surges. Several areas in Karachi and Multan faced intermittent load shedding throughout the day.
