Delhi Braces for Heatwave: Temperatures to Hit 40°C as Relief Days End
Delhi’s brief spell of cooler weather has ended, with the India Meteorological Department (IMD) forecasting temperatures reaching 40°C starting May 12, 2025. The capital is gearing up for a severe heatwave, replacing recent cloudy skies and light showers with relentless heat and humidity. As residents prepare for challenging days ahead, authorities are issuing advisories to mitigate health risks. This article explores the heatwave’s onset, its impacts, and essential precautions.

Heatwave Onset and Weather Shift
The IMD attributes the sudden temperature spike to clear skies and dry northwesterly winds, which have replaced the moist easterly flows that brought temporary relief. Daytime temperatures are expected to hover around 40°C, with nighttime lows offering little respite at 28–30°C. Humidity levels, projected to reach 60%, will make the heat feel more oppressive, increasing discomfort. The heatwave is likely to persist for at least a week, with no immediate forecast for rain. Delhi’s urban heat island effect, driven by concrete infrastructure, will exacerbate conditions, particularly in densely populated areas.

Health and Infrastructure Challenges
Prolonged exposure to such high temperatures poses risks like heatstroke, dehydration, and exhaustion, especially for the elderly, children, and outdoor workers. The Delhi government has activated heat action plans, setting up oral hydration stations and cooling centers in public spaces. Power demand is expected to surge as air conditioners and coolers run nonstop, straining the city’s electricity grid. Last year, peak summer demand hit 8,000 MW, and officials are urging energy conservation to prevent outages. Water scarcity in some areas may also worsen, prompting calls for judicious usage.

Precautions and Public Response
The IMD advises residents to avoid outdoor activities between 11 AM and 4 PM, stay hydrated, and wear lightweight clothing. Schools may shift to early schedules or online classes to protect students. Social media platforms like X show Delhiites sharing tips on coping with the heat, from using wet towels to scheduling errands for cooler hours. As the city braces for this scorching phase, proactive measures and community resilience will be key to navigating the heatwave safely.
