Probable heat wave, maximum temperature around 42°C


Heatwave conditions remain on the Indian Meteorological Department (IMD) forecast for Delhi on Tuesday. The maximum temperature should be 42 degrees Celsius. The city has so far recorded seven days of heatwave this month.

The maximum temperature recorded Monday at the Safdarjung meteorological observatory was 41.6 degrees Celsius, five degrees above normal for this time of year, marking a heat wave at the observatory on Monday. Ridge and Pitampura weather stations recorded an even higher temperature of 42.9 degrees Celsius, while Najafgarh observatory recorded 43 degrees Celsius.

The minimum temperature over the past 24 hours was 23.7 degrees, two degrees above normal. Over the next six days, the minimum temperature, which is usually recorded at night, could range from 22 to 24 degrees Celsius.

Under the influence of a disturbance from the west, cloudy skies and light precipitation are forecast for Wednesday and Thursday. That could provide respite from the heat wave, with the maximum temperature expected to drop a few notches to 39 degrees Celsius on Thursday and Friday. Heatwave conditions are expected to ease with the approach of westerly disturbances and associated wind conditions and cloudy skies, according to the IMD forecast Tuesday morning.

No significant change is expected in the maximum temperature over northwest India in the next 24 hours, but it could drop by 2 to 4 degrees in the next three days, according to forecasts. The city recorded no rain in March when the normal rainfall amount for the month was 15.9mm. Safdarjung Meteorological Observatory has yet to record any rainfall in April as well.

Meanwhile, the air quality index (AQI) in Delhi was 257 on Monday, in the “poor” category, with PM10 as the main pollutant. It is expected to remain in the “poor” category on Tuesday and Wednesday, according to the Air Quality Early Warning System forecast.
