Early Heatwave Hits South Asia, Signaling a ‘New Normal’ Amid Climate Change

South Asia is experiencing an early and intense heatwave, with India and Pakistan facing temperatures far above seasonal averages in April, The Guardian reported. Typically, the region’s heat peaks in June, but this year, temperatures have soared prematurely. Delhi has recorded temperatures exceeding 40°C, up to 5°C above normal, while Jaipur reached 44°C, causing heatstroke cases among outdoor workers. In Pakistan, Shaheed Benazirabad hit an extreme 50°C, nearly 8.5°C above the April average.

Experts attribute this dangerous early heat to human-driven climate change, with reports showing spring heatwaves are becoming a regular and worsening phenomenon. Urban areas like Delhi and Islamabad now experience temperatures up to 3°C hotter than nearby rural zones, exacerbating risks. The Indian Meteorological Department has reported an above-normal number of heatwave days, with further increases expected.

Authorities in Delhi have issued emergency guidelines to protect vulnerable populations, including school children and outdoor workers. However, infrastructure remains poorly adapted for such extreme heat, and economic inequality affects people’s ability to cope.

Climate scientists warn that without drastic emissions reductions and improved climate resilience—such as better-insulated housing and energy-efficient designs—the frequency and severity of heatwaves will continue to rise, posing severe health and economic challenges across the region.
