South Asia Scorched by Unprecedented Heat

A record-breaking heatwave is currently affecting South Asia, with temperatures reaching dangerous highs across India, Pakistan, and Bangladesh. This event, which began in late April 2026, has disrupted daily life for hundreds of millions and resulted in multiple heat-related fatalities, including at least 10 reported in Pakistan's Karachi on Tuesday alone. The intensity, duration, and geographic spread of this heatwave are considered unprecedented by meteorological agencies and scientists.

High-pressure systems are trapping hot air, preventing cooling and leading to relentless solar heating. Contributing factors include weak pre-monsoon rains and lingering El Nino-like patterns, which suppress natural cooling mechanisms. The World Meteorological Organization (WMO) has indicated a high confidence in the onset of El Nino conditions between May and July, which, while not increasing the frequency of such events, can worsen their impact.

Temperatures have exceeded 45-50 degrees Celsius (113-122 degrees Fahrenheit) in some areas. India's Meteorological Department forecasts higher-than-average temperatures, with some regions experiencing increases of three to five degrees Celsius (5.4 to nine degrees Fahrenheit) above normal.

In Pakistan, Karachi recorded 44 degrees Celsius (111 degrees Fahrenheit), its highest since 2018, and cities like Jacobabad and Sukkur are projected to reach 46 degrees Celsius (114.8 degrees Fahrenheit) later this week.
