Delhi Records Hottest May Night in 14 Years: How to Keep Yourself Safe During the Extreme Delhi NCR Heatwave
The Delhi and the greater NCR area are suffering from record-breaking heat during the summer of 2026. The city recorded its hottest May overnight temperatures in almost fourteen years. As indicated by weather data collected so far, the lowest recorded temperature overnight in Delhi was just under 31.9 degrees Celsius, which provided very little cooling relief from heat exposure after sunset.
The India Meteorological Department has issued orange warnings throughout the Delhi NCR area, as many locations experience daytime temperatures around 45–46 degrees Celsius.
Why Warm Nights Are Dangerous
Nighttime temperatures are usually cool enough to allow the body to recover from heat exposure during the day. However, during “warm nights,” heat continues to be trapped (i.e., heat retention in concrete) within the area, increasing thermal stress on the body; this leads to dehydration, exhaustion and heatstroke.

Final Words
In closing, this record-breaking May evening in Delhi (nearly 14 Years) has become yet another reminder of the growing risk of urban heatwaves across India, which is exposed to more and more intense urban heatwaves as time goes on. Experts have indicated that because of the record high daytime temperatures of 46 degrees Celsius, combined with the lack of a chance to cool down in the nighttime hours, hydration, exposure to minimum levels of heat, and awareness of symptoms associated with heatstroke; are now essential survival items to help individuals survive through this current NCR heat emergency.
