Karachi struggles under brutal new reality of extreme heat

The Lead

An intense and prolonged heatwave has been causing misery for millions across Pakistan and India. In southern Pakistan, particularly in Sindh, daytime temperatures have frequently crossed 44C to 46C, forcing residents indoors during peak afternoon hours and severely affecting outdoor labourers, transport workers, and farming communities.

Karachi's Struggle with Extreme Heat

In Karachi, the city usually moderated by sea breezes from the Arabian Sea, temperatures have crossed 40C on multiple occasions. The Pakistan Meteorological Department recorded a maximum temperature of 44.1C in Karachi, the city's highest reading since 2018. Meteorologists have warned that hotter days may still be to come.

The Impact on Local Communities

The impact has been particularly severe in Karachi's coastal settlements, where prolonged electricity outages and water shortages have compounded the effects of extreme heat. In Ibrahim Hyderi, one of the city's largest fishing communities, residents say survival is becoming increasingly difficult.

Health Crisis and Climate Change

Climate experts warn that rising temperatures are no longer isolated incidents but part of a worsening long-term trend driven by climate change and rapid urbanisation. The World Weather Attribution group found that human-caused climate change approximately tripled the probability of an event like this happening, making it no longer exceptional in today's climate.

The Future Outlook

Climate specialists are urging immediate intervention, including the establishment of public cooling centres, expanded access to drinking water, emergency medical preparedness, and large-scale urban tree plantation drives. For many people, the crisis is no longer a warning about the future; it is already reshaping everyday life — turning extreme heat from a seasonal hardship into a persistent struggle for survival.
