New Delhi: The heat wave intensified in Delhi on Thursday and the maximum temperature crossed 40 degrees Celsius. The IMD had earlier predicted that there would be no respite from the scorching heat for at least a week. Parts of the national capital have been in the grip of heat wave since March last week and their maximum temperature is above 40 degrees Celsius.

Delhi’s Safdarjung Observatory, which is considered the city’s official marker, recorded a maximum temperature of 39.6 degrees Celsius last Wednesday, the highest so far in the season.


IMD officials said hot weather conditions in northwest India have become “severe” due to the prolonged drought. “Last heat is likely to prevail over most parts of Northwest India and Madhya Pradesh during the next five days.”

For plains, a “heatwave” is declared when the maximum temperature is more than 40 degrees Celsius and at least 4.5 degrees above normal. According to the IMD, if the departure from normal temperature is more than 6.4 degrees, a “severe” heatwave is declared.

Important Updates from Meteorological Department:

  1. India recorded its hottest March in 122 years, with sweltering heat lashing large swathes of the country during the month.
  2. The Met department attributed the unusual heat to the absence of an active Western Disturbance over North India and lack of rainfall due to any major system in South India.
  3. The entire country recorded 8.9 mm of rainfall, which was 71 per cent less than its long period average of 30.4 mm.
  4. This was the third lowest rainfall in March since 1901, after 7.2 mm in 1901 and 8.7 mm in 1908.
  5. “All over the country, the average maximum temperature (33.10 degree Celsius) was recorded in March 2022, which is the highest in the last 122 years,” the IMD said.
  6. In March 2010, the maximum temperature of the country was recorded at 33.09 °C.

Experts have attributed the lack of rainfall due to dry westerly winds to the hot weather. Delhi recorded zero rainfall in March – the first time since 2018. Generally, the month receives an average of 15.9 mm of rain.
