The Pakistan Meteorological Department (PMD) has issued a new heatwave warning for Karachi, predicting scorching temperatures, high humidity, and the absence of cooling sea breezes from today through April 23.
Met officials reported a morning temperature of 27°C with 56% humidity, adding to the discomfort. Forecasts suggest the mercury could soar between 37°C and 41°C in the coming days.
While wind speeds may increase to 30–35 km/h, they are unlikely to bring much relief, as the city continues to be affected by hot, dry gusts from Balochistan.
The usual sea breeze, which typically cools the coastal city, might not return during the day, worsening the heat. This severe weather is caused by dropping air pressure linked to a western weather system moving into Pakistan.
On Saturday, Karachi recorded a high of 36.5°C with lower humidity at 26%, while Jacobabad scorched at 45°C, 6.5°C above average, becoming one of the hottest places in the country.
PMD spokesperson Anjum Nazir Zaighum said, “The western weather system affecting air pressure was driving the current heatwave.”
He mentioned that although the sea breeze could resume after sunset, its continued absence during the day would intensify the conditions.
Authorities have urged the public to take preventive steps, including staying indoors during peak heat, avoiding unnecessary outings, staying hydrated, and taking special care of children, seniors, and women.
