The Pakistan Meteorological Department said that a severe heatwave will affect Sindh province from May 25 to May 31, 2026 [4].
The timing of the extreme heat coincides with the Eid-ul-Azha holiday period, potentially complicating public safety and health efforts during a major national celebration.
Officials said that a high-pressure system developing in the upper atmosphere is expected to intensify [5]. This weather pattern is forecast to drive temperatures four to six°C above normal levels [1].
Forecasts for peak temperatures vary by agency. Some reports indicate that temperatures could reach up to 50°C in many cities [2]. Earlier alerts from the National Disaster Management Authority suggested that maximum temperatures may cross 42°C [3].
The National Disaster Management Authority issued its own alert period running from May 19 to May 26, 2026 [5]. Provincial officials and meteorological agencies continue to monitor the situation as the heatwave begins today.
In Karachi, temperatures during the Eid holidays are expected to range between 35°C and 38°C [6]. This is lower than the peaks expected in other parts of the province, but still contributes to the regional heat stress.
Government agencies are coordinating responses to mitigate the impact of the rising heat. The PMD alert specifically targets the final week of May to ensure provincial readiness [4].
“Temperatures could reach up to 50°C in many cities”
The discrepancy between the NDMA and PMD forecasts—ranging from 42°C to 50°C—highlights the volatility of the current weather system. Because this event overlaps with Eid-ul-Azha, the surge in temperature poses a significant risk to public health and livestock management during a period of high human mobility and outdoor activity.
