The Pakistan Meteorological Department (PMD) has forecast a fresh heatwave for Karachi beginning Sunday, with maximum temperatures likely to surge to 40 degrees Celsius — around 4 to 6 degrees above the city’s normal daytime average for this time of year.
A senior meteorologist said the rising temperatures are attributed to a change in the atmospheric pressure system over Sindh.
"Due to the high-pressure area shifting away from the upper and central parts of Sindh, sea breeze is expected to halt from Sunday, leading to increased heat intensity in Karachi," he said.
He added that while the heatwave will affect Karachi starting tomorrow, the movement of the weather system towards southern Sindh will help bring relief to other parts of the province from Saturday onwards.
The Met Office has issued an advisory urging citizens, particularly children, women, and the elderly, to avoid unnecessary exposure to the sun, remain hydrated, and take precautionary measures during the hot spell.
Karachi recorded a maximum temperature of 34.3°C on Friday, while Saturday's forecast suggests highs ranging from 36°C to 38°C, accompanied by hot and humid conditions.
Meanwhile, several cities in the interior of Sindh continued to swelter under intense heat. Dadu and Shaheed Benazirabad topped the list with a searing 46.5°C, followed closely by Padidan at 46°C. Other cities, including Larkana (45.6°C), Mohenjo Daro and Khairpur (45.5°C), Sukkur and Rohri (45°C), Hyderabad and Mirpurkhas (42°C), and Badin (39°C), also reported significantly high temperatures.
