Karachi experienced severe heat conditions on Wednesday as the city’s feels-like temperature surged to 54°C despite the maximum recorded temperature reaching 37.4°C, according to data released by the Pakistan Meteorological Department.
The data showed that the heat index steadily increased from 49°C at around 1pm to 54°C by 3pm, driven by high humidity levels. Relative humidity was recorded at 79% in the morning and 65% in the evening, while the minimum temperature remained at 30°C.
Several districts across Sindh witnessed even harsher weather conditions. Jacobabad recorded the highest temperature at 49.5°C, followed by Dadu at 49°C.
Temperatures in Paddidan and Sukkur reached 47°C, while Mohenjo Daro, Larkana, and Shaheed Benazirabad recorded 46.5°C. Rohri reached 46°C, Khairpur 45.5°C, and Sakrand 45°C.
Chief Meteorologist Ameer Hyder Laghari said relief is expected after Friday as the high-pressure system affecting the region gradually weakens.
He noted that temperatures in Karachi are likely to fall between 34°C and 36°C in the coming days, though no rainfall is forecast for the city.
Laghari added that Karachi’s highest-ever temperature for June remains 47°C, recorded on June 18, 1979.
Speaking about protection from heat-related illnesses, Dr Nadeemullah Khan emphasized that staying hydrated is the most important measure during extreme heat.
He advised people to avoid sugary drinks, caffeinated beverages, tea, coffee, and alcohol, as these can accelerate fluid loss. He also recommended limiting outdoor activities during peak heat hours and spending time in air-conditioned or cooled environments whenever possible.
According to Dr Khan, children and the elderly remain the most vulnerable groups during heatwaves.
He warned that children should never be left inside parked vehicles and outdoor activities should be restricted to cooler hours of the day.
Frequent water breaks are essential for preventing heat-related illnesses.
For elderly individuals, reduced cardiovascular capacity, mobility challenges, and living in poorly ventilated homes increase the risk of heat-related complications.
Dr Khan urged families and community health workers to conduct regular welfare checks on elderly residents during periods of extreme heat.
Health experts continue to advise the public to remain hydrated, avoid direct sun exposure, wear light clothing, and seek medical attention immediately if symptoms of heat exhaustion or heatstroke develop.
