Karachi braces for heatwave as mercury may soar to 41°C today

The Pakistan Meteorological Department (PMD) on Saturday warned of a heatwave-like situation in Karachi beginning Sunday, with daytime temperatures expected to soar as high as 41°C due to a halt in the sea breeze and shifting wind patterns.

According to Anjum Zaigham, deputy director at the PMD, temperatures across the city will remain 4 to 6 degrees Celsius above normal from Sunday, April 21, to Wednesday, April 24.

“We expect hot to very hot and dry weather during this period,” he said, adding that northwesterly winds will temporarily cut off the sea breeze, worsening the heat conditions.

While the humidity levels are forecast to remain low, PMD officials clarified that the “feel-like” temperature may not be as oppressive as it typically is during high-humidity heatwaves.

Humidity in the morning is expected to range between 40 and 60 percent, and it may drop to 15 to 25 percent in the evening over the next few days.

The maximum temperature on Sunday and Monday is expected to range between 39°C and 41°C, while the minimum temperature may hover between 25°C and 27°C, according to the official forecast.

The PMD has advised the general public—particularly children, the elderly, and women—to take precautionary measures during the hot spell. Citizens are urged to avoid direct sun exposure, especially during peak afternoon hours, and stay well-hydrated.

To prevent heatstroke and sunstroke, health experts recommend wearing loose, light-coloured clothing, covering the head with a cap or damp cloth, and avoiding strenuous activities outdoors.

People working outdoors should take frequent breaks in shaded areas, drink ORS (oral rehydration salts) or water frequently, and avoid beverages that cause dehydration such as tea, coffee, and sugary sodas.

Heatwaves have increasingly become a seasonal concern in Karachi due to rapid urbanization, shrinking green spaces, and rising global temperatures. In past years, extreme heat conditions have led to multiple casualties, particularly among those without access to electricity, shelter, or drinking water.

The PMD has shared its forecast with city authorities, including the mayor of Karachi, Rescue 1299, PDMA Sindh, and other emergency services to prepare and respond in case of any heat-related emergencies.
