Context: India is likely to experience a warmer summer this year with El Nino conditions predicted to continue at least until May, according to the India Meteorological Department.

Key Points of IMD

  • Heatwave Prediction: More heatwave days than normal are predicted over northeast peninsular India, including Telangana, Andhra Pradesh, north interior Karnataka, as well as many parts of Maharashtra and Odisha.
  • Above-Normal Rainfall: The country is likely to record above-normal rainfall in March, exceeding 117 percent of the long-period average of 29.9 mm.
  • Above-Normal Temperatures: India is likely to see above-normal maximum and minimum temperatures in most parts of the country from March to May.
  • Absence of Heatwave Conditions: Heatwave conditions are not expected over north and central India in March.
  • Prediction of La Nina: La Nina conditions, generally associated with good monsoon rainfall in India, are likely to set in by the second half of the monsoon season.
  • February's Record Minimum Temperature: India recorded an average minimum temperature of 14.61 degrees Celsius in February, the second highest in the month since 1901.
