Delhi is witnessing a notable rise in temperatures this summer season, with daytime readings reaching between 39°C and 41°C in various parts of the national capital. Some areas have recorded maximum temperatures surpassing 40°C, indicating a strong start to the warmer months. The Safdarjung observatory, which is the principal weather station for the city, has reported temperatures nearing the 40°C mark, signalling an early onset of heat in 2026.

This rise in temperature follows a relatively mild start to April, where occasional rain and cloud cover kept the mercury levels manageable. Presently, however, clear skies coupled with dry northwesterly winds are contributing to a rapid increase in ground temperatures.

Historically, the Safdarjung observatory has recorded extremes of temperature, including a staggering 46.8°C in 2024, which marked the highest temperature documented there in 79 years. The current heat trends could potentially lead to similar records if conditions persist.

Forecast for Upcoming Days

The India Meteorological Department (IMD) has forecasted that maximum temperatures in Delhi are expected to rise by 2-3°C over the next three days, before experiencing a slight decrease of 1-2°C. Despite this minor projected drop, temperatures are anticipated to remain 2-4°C above normal for this time of year, increasing public discomfort.

Minimum temperatures, essential for assessing nighttime warmth, are also on the rise, contributing to overall discomfort during the evenings. As of April 16, the IMD has not declared an official heatwave, although conditions are being closely monitored. A heatwave is commonly classified when maximum temperatures reach or exceed 40°C and significantly surpass normal levels for several consecutive days.

The current climate pattern reflects warnings made earlier by the IMD, which had predicted a surge in heatwave days across various regions in northwest, central, eastern, and southeastern peninsular India from April to June.

Precautions and Recommendations for Residents

As temperatures climb, residents are urged to take precautions to mitigate heat-related discomfort and health risks. Regular hydration is vital, and individuals are advised to drink plenty of water throughout the day, even in the absence of thirst. It is also recommended to limit outdoor activities between noon and 4 pm when sunlight is at its strongest.

Residents should opt for loose-fitting, light-coloured cotton clothing and consider using umbrellas, caps, or scarves to shield themselves from direct sunlight. Specific attention should be given to vulnerable groups, including the elderly, young children, and outdoor workers, who should take regular breaks in shaded, cooler environments.

Additionally, farmers and daily-wage labourers may need to adjust their schedules to conduct heavy tasks during early morning or evening hours when temperatures are more bearable. This early surge in temperature is a clear indication that the summer of 2026 is approaching with intensity.

By following the guidance provided by the IMD and remaining vigilant, residents can better manage the rising temperatures in the days ahead, ensuring safety and comfort as the season progresses.
