Mercury likely to hit 41°C as Karachi braces for heatwave till 23rd: PMD

The Pakistan Meteorological Department (PMD) has issued a fresh heatwave alert for Karachi, warning of soaring temperatures, stifling humidity, and minimal sea breeze from today onwards. The intense weather conditions are expected to persist until April 23.

According to Met officials, Karachi recorded a morning temperature of 27°C with humidity levels at 56 per cent, significantly amplifying the sense of discomfort.

Meteorologists have forecast that daytime temperatures may rise further, ranging between 37°C and 41°C over the coming days.

Wind speeds, currently recorded at 9 km/h, are expected to accelerate to 30–35 km/h.

However, officials noted this increase would offer little relief as hot, dry winds from Balochistan’s deserts continue to dominate.

The sea breeze, which typically brings cooling relief to the coastal city, may cease entirely during the day, contributing to the severe heat.

The ongoing heatwave has been attributed to a gradual drop in air pressure, a phenomenon linked to a Western weather system entering the country.

On Saturday, the city’s maximum temperature had already climbed to 36.5°C, accompanied by a relatively lower humidity level of 26 per cent.

In contrast, Jacobabad in interior Sindh recorded a blistering 45°C — 6.5 degrees above normal — marking it as one of the hottest spots in the country.

PMD spokesperson Anjum Nazir Zaighum explained that the western weather system affecting air pressure was driving the current heatwave.

He added that while the sea breeze may return after sunset, if it remains inactive during the day, the situation could worsen considerably.

The Met Office has advised the public to adopt precautionary measures. Citizens are urged to stay indoors during peak heat hours, avoid unnecessary travel, and drink plenty of water to stay hydrated. Special care has been recommended for vulnerable groups including children, the elderly, and women.
