KARACHI: A heatwave is expected to hit the Pakistani provinces of Sindh and Punjab in May and June, the National Disaster Management Authority (NDMA) said on Thursday, advising citizens in high-risk districts to take precautions.
Increased exposure to heat, and more heatwaves, have been identified as one of the key impacts of climate change in Pakistan, with people experiencing extreme heat and seeing some of the highest temperatures in the world in recent years. The South Asian country of more than 241 million, one of the ten most vulnerable nations to climate change impacts, has also recently witnessed untimely downpours, flash floods and droughts.
In a statement released on Thursday, the NDMA listed Umerkot, Tharparkar, Tando Allayar, Matiari and Sanghar in Sindh and the Bahawalpur and Rahim Yar Khan districts in Punjab as at risk from heat waves.
“Temperatures could surge to 40 degrees Celsius from May 15-30,” the statement said. “Similarly, temperatures could rise to 45 degrees Celsius in June.”

Climate change-induced extreme heat impacts human health in multiple ways. Direct effects of exposure to extreme heat and heatwaves can include heat-related illnesses such as heat cramps, heat exhaustion, heatstroke, and hyperthermia. It can make certain chronic conditions worse, including cardiovascular, respiratory, and cerebrovascular disease and diabetes-related conditions, and can also result in acute incidents, such as hospitalizations due to strokes or renal disease.
According to the Global Climate Risk Index, nearly 10,000 Pakistanis have died while the country has suffered economic losses worth $3.8 billion due to climate change impacts between 1999 and 2018. A deadly heatwave that hit Pakistan’s largest city of Karachi, the capital of Sindh, claimed 120 lives in 2015.
In 2022, torrential monsoon rains triggered the most devastating floods in Pakistan’s history, killing around 1,700 people and affecting over 33 million, a staggering number close to the population of Canada. Millions of homes, tens of thousands of schools and thousands of kilometers of roads and railways are yet to be rebuilt.
