Karachi recorded a scorching 41°C on Monday, marking the city’s highest September temperature in a decade. Hot and humid conditions continued to grip Sindh throughout the week. According to the Pakistan Meteorological Department, Karachi’s all-time high for September remains 43°C, recorded back in 1951. The city also reached 42.7°C on September 20, 2015.

However, the heat wasn’t limited to Karachi alone. Nine cities across Sindh recorded temperatures of 40°C or higher. Shaheed Benazirabad, Hyderabad and Khairpur emerged as the hottest cities in the province, each reaching 42°C.

Chief Meteorologist Ameer Hyder Laghari explained that a persistent low-pressure area had blocked the sea breeze, driving the ongoing heat and humidity. Still, he added that temperatures are expected to fall starting Tuesday, since the low-pressure system has nearly dissipated.

The weather system brought rainfall to some eastern parts of the province. Meanwhile, most areas, including Karachi, missed out on monsoon showers entirely. Additionally, the PMD has already forecast a largely dry monsoon season for the region.

Laghari also noted that El Niño conditions are contributing to broader regional atmospheric warming. El Niño refers to a natural climate pattern tied to warmer surface waters in the tropical Pacific Ocean. Therefore, this pattern may continue influencing weather trends across the country in the coming weeks.

Karachi’s temperature is expected to hover between 36°C and 38°C on Tuesday. Furthermore, relative humidity should remain between 70% and 80% in the morning. It will likely drop to between 45% and 55% by evening.

Finally, residents across Sindh should brace for continued warmth even as this particular heat spike eases. The Karachi September temperature record adds to a growing pattern of unusual seasonal heat across the province.
