Delhi Swelters as Mercury Soars to 38.2°C, Hottest Day of the Year Recorded
New Delhi witnessed its hottest day of 2024 on Tuesday, with the maximum temperature reaching a scorching 38.2°C. This intense heat serves as a stark preview of what could be a severe summer ahead, as meteorological forecasts predict the mercury will continue its upward trajectory in the coming days.
Temperature Surge and Forecasted Peak
Tuesday's peak temperature was two degrees above the seasonal normal, surpassing the previous high of 36.8°C recorded on April 2 and March 11 this year. The India Meteorological Department (IMD) has projected a steady rise, with temperatures expected to approach 40°C on Wednesday, 41°C on Thursday, and potentially touch 42°C by Friday.
Despite these alarming figures, the IMD has not yet issued a formal heatwave alert for the capital. According to official criteria, a heatwave is declared when temperatures exceed 40°C with a departure of at least 4.5°C above normal, or when they cross 45°C in the plains.
Weather Patterns Driving the Heat
The recent spike in temperatures is attributed to a shift in weather conditions. After a relatively mild start to summer due to frequent rainfall from western disturbances, the region is now experiencing calm winds and cloudless skies, which have accelerated the heat build-up.
An IMD official explained, "We observed stronger surface winds on Sunday and Monday, which helped keep temperatures in check. However, as winds slowed on Tuesday and the skies remained clear, temperatures rose sharply."
The temperature increase has been gradual but consistent throughout April:
- April 9: 30.8°C
- April 10: 32.8°C
- April 11-12: 34.7°C
- April 13: 36.1°C
- April 16 (Tuesday): 38.2°C
Expert Warnings and Historical Context
Weather experts caution that the current conditions could soon lead to heatwave declarations across northwest India. Mahesh Palawat of Skymet Weather noted that low wind speeds and persistent clear skies are key factors driving the heat accumulation.
Historically, April has seen even higher temperatures in Delhi. Last year, the city recorded 42.1°C on April 26, while the all-time April record remains 45.6°C, set in 1941.
Air Quality and Regional Weather Outlook
Meanwhile, Delhi's air quality remained within the 'moderate' category on Tuesday, with an Air Quality Index (AQI) of 167, slightly higher than Monday's reading of 149. Forecasts indicate that AQI levels are likely to stay moderate through the end of the week.
A weak western disturbance is expected to affect the western Himalayan region and parts of north Punjab from Wednesday night, but meteorologists say it is unlikely to bring any significant relief to Delhi-NCR's weather conditions.
The combination of rising temperatures and moderate air quality poses a dual challenge for residents, highlighting the need for precautionary measures as summer intensifies.
