An intense and prolonged heatwave has been causing misery for millions across Pakistan and India.

In southern Pakistan throughout April and May, temperatures have risen far above seasonal norms. 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.

India has also been experiencing intense heatwave conditions in recent weeks, particularly across Rajasthan, Gujarat, Maharashtra and parts of northern and central India , where temperatures in several cities have crossed 45C. Authorities in multiple states have issued heatwave alerts as extreme temperatures increase health risks, strain electricity supplies and disrupt daily life for millions. Climate experts say the recurring heatwaves across south Asia reflect a broader pattern of rising temperatures and increasingly severe weather linked to the climate crisis.
