IMD warns of extreme heat in Apr-Jun

India will experience extreme weather conditions in the form of “above normal heatwave days” during the hot weather season which starts in April and continues through June due to EL Nino conditions, according to the India Meteorological Department (IMD). However, this is not likely to cause any damage to wheat, which is the main rabi crop, as it has reached close to harvest.

“There is no heatwave warning in wheat-producing areas, except Madhya Pradesh, where around 90% of the wheat crop has been harvested,” said IMD director general Mrutyunjay Mohapatra on Monday.

The government is expecting a yield of 112 mt of wheat this year against last year’s 110 mt as the area under cultivation has gone up by 1.21%.

El Nino conditions are likely to persist during April-June, thereafter shifting towards La Nina (generally associated with good monsoon rainfall in India) during the second half of the monsoon months (July-September), the IMD chief said. However, he did not comment on the expected rainfall situation during the monsoon season this year.

IMD Warns of Extreme Heat in Apr-Jun

El Nino is the periodic warming of waters in the central Pacific Ocean which is known to cause erratic and less rainfall in India. It led to patchy and erratic monsoon in 2023 thereby reducing India’s foodgrain production by 6.1% in the 2023-24 crop year (July-June).

Several parts of the country such as the southern peninsula, adjoining northwest India, central India and some parts of east India and plains of northwest India are likely to face above normal heatwave days, said Mohapatra.

These areas are likely to face 2-8 days of heatwave against the normal of 1-3 days during April, he added.

RAINFALL

Rainfall during April is expected to be normal between 88% to 112% of the long period average over most parts of the northwest, central and peninsular India. However, eastern and western coasts parts of eastern and northeastern India and southern part of peninsular India are likely to get below normal rainfall.

During the hot weather season, April-June, both minimum and maximum temperatures are expected to be above normal in most parts of the country.
