New Delhi: Delhiites have been in the grip of scorching heat for the past few weeks with the maximum temperature hovering around 40-42 degree Celsius. The India Meteorological Department (IMD) on Sunday issued a heat wave warning for several parts of the national capital. The weather monitoring agency said that the maximum temperature in Delhi is likely to reach 42 degrees Celsius.


The meteorologist has also predicted clear skies during the day, but heat wave conditions are likely at many places with “severe” heat wave conditions at a few places across the city.

  1. The minimum temperature in Delhi on Sunday was recorded at 23.5 degrees Celsius, four notches above normal.
  2. The relative humidity was recorded at 32 per cent at 8.30 am.
  3. According to the IMD, the maximum temperature is expected to reach 42 degrees Celsius in the national capital on Sunday. The Meteorological Department has forecast clear skies for the day, but heat wave conditions are likely at many places with “severe” heat wave conditions at a few places in the city.

  8. IMD uses four color codes for weather warnings – “green” (no action required), “yellow” (watch and stay updated), “orange” (be prepared) and “red” (take action).
  9. Saturday’s maximum temperature at Delhi’s base station Safdarjung Observatory was 42.4 degrees Celsius, eight degrees above normal for this time of year.

In Haryana’s Faridabad, the mercury was recorded at 45.2 degree Celsius on Saturday. IMD said that due to cloudy sky, there may be some respite from the scorching heat from Tuesday. Parts of the national capital have been in the grip of heat wave since last one week. IMD officials said hot weather conditions in northwest India have become “severe” due to the prolonged drought. The Meteorological Department said that Northwest India and adjoining parts of Central India are predicted to see more intense and persistent heatwave conditions in April.


Mahesh Palawat, Vice President (Meteorology and Climate Change), Skymet Weather, said on Saturday that it is an aberration that the maximum temperature has crossed the 45 degree Celsius mark in some parts of northwest India in the first 10 days of April. He said there is a good chance that Delhi may record more heatwave days in April than usual.

Palawat said the capital has already recorded three heatwave days this month and heat wave conditions are likely to last for two to three days. For the plains, a “heatwave” is declared when the maximum temperature exceeds 40 degrees Celsius and is at least four and a half degrees above normal. According to the IMD, if the departure from normal temperature is more than 6.4 degrees, a “severe heat wave” is declared.

This year, India recorded its hottest March in 122 years, with the country witnessing scorching heat during the month. The Met department attributed the heat to the absence of an active Western Disturbance over North India and lack of rain due to any major system over the southern parts of the country.
