The India Meteorological Department has predicted similar conditions for the next two days, keeping Delhi in the grip of heat wave for the fourth consecutive day on Sunday. The Meteorological Department has issued a warning of severe heat wave in the city on Monday and has issued an ‘orange’ alert.

IMD uses four color codes for weather warnings – green (no action required), yellow (watch and stay updated), orange (be prepared) and red (take action). The capital has recorded four heatwave days in April this year so far, which is equal to the number of such days in the month in 2017.


In the plains, a ‘heatwave’ is declared when the maximum temperature exceeds 40 degrees Celsius and is 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 heat wave’ is declared.

The Sports Complex station was the hottest place in the city with a maximum temperature of 44.1 degree Celsius. The mercury went above 42 degree Celsius at most places.


The Safdarjung Observatory, which is considered the city’s official marker, recorded a maximum temperature of 41.8 degrees Celsius, six notches above normal. The maximum temperature on Saturday was recorded at 42.4 degrees Celsius, the highest in five years in April.

This is also the first time in 72 years that Delhi has recorded such a high temperature in the first fortnight of April.


The maximum temperature in the capital was recorded at 43.2 degree Celsius on April 21, 2017. The highest ever maximum temperature of the month was recorded on April 29, 1941 at 45.6 °C.

IMD said that due to cloudy sky, there may be some respite from the scorching heat from Tuesday.

Heat wave conditions have been prevailing in parts of the national capital for the past one week with the maximum temperature hovering above 40 degrees Celsius.

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 that it is an aberration that the maximum temperature has crossed the 45 degree mark in some parts of northwest India in the first 10 days of April.

No pre-monsoon activity including dust storm and thundershowers has occurred over the region so far. He said even the long-range models did not predict any significant weather system in the next 15 days.

Palawat said that there is a good chance that the number of hot days in Delhi in April may be above normal.

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 South India.

The entire country recorded 8.9 mm of rainfall, which was 71 per cent less than its long period average of 30.4 mm. This was the third lowest rainfall in March since 1901, after 7.2 mm in 1901 and 8.7 mm in 1908.
