Brace for a Hotter Summer: India Faces Above-Normal Heatwave Risk
India is bracing for a potentially scorching summer, with the India Meteorological Department (IMD) forecasting above-normal heatwave days across much of the country between March and May. The forecast, released on Saturday, highlights a significant risk to public health and essential services.
Regions at Highest Risk
Several regions are particularly vulnerable to the anticipated heat. These include West Rajasthan, Gujarat, Haryana, Punjab, southern and eastern Maharashtra, eastern Uttar Pradesh, Bihar, Jharkhand, Gangetic West Bengal, Odisha, Chhattisgarh, Telangana, Andhra Pradesh and parts of north Karnataka and north Tamil Nadu. Residents in these areas should prepare for prolonged periods of high temperatures.
Impact on Daily Life and Vulnerable Populations
The IMD warns that the increased likelihood of heatwave conditions could strain vital resources. “The increased likelihood of heatwave conditions may pose significant risks to public health, water resources, power demand, and essential services,” stated IMD Director General Mrutyunjay Mohapatra. Elderly individuals, children, outdoor workers, and those with pre-existing medical conditions are especially at risk and should take precautions.
March Weather: A Mixed Bag
While the long-term outlook points to a hot summer, March is expected to bring a more varied weather pattern. Many parts of the country will likely experience normal to below-normal maximum temperatures, with the exception of northeast and east India, as well as parts of the Western Himalayan region and central and peninsular India. Normal minimum temperatures are expected across most of the country, except for northwest India, the south peninsula, and along the east coast, where temperatures may be normal to below normal.
Rainfall Predictions for March
March rainfall is most likely to be normal across India, averaging around 29.9 mm, based on data from 1971 to 2020. However, northeast India, and some parts of northwest and east-central India may experience below-normal rainfall.
El Niño and La Niña: The Climate Drivers
Currently, weak La Niña conditions are present in the equatorial Pacific. However, forecasts suggest a potential return to neutral El Niño Southern Oscillation (ENSO) conditions in the coming months. These shifts in climate patterns can significantly influence weather conditions globally, including India’s monsoon season.
Looking Back: February’s Weather Patterns
February 2026 saw the lowest rainfall across India since 2001. The absence of active western disturbances and their interaction with easterly winds contributed to subdued snow and rainfall during the month. Maximum temperatures were normal to above normal in most areas, while minimum temperatures were normal to above normal, except in the eastern peninsula and east-central India. February 2026 also marked the 10th highest maximum temperature, the third highest minimum temperature, and the fifth highest mean temperature since 1901.
Understanding Heatwaves: A Closer Look
What is a Heatwave?
A heatwave is a period of abnormally hot weather, typically lasting two or more days. The IMD declares a heatwave when the maximum temperature reaches 40°C or higher in the plains, or 30°C or higher in hilly regions. Heatwaves can be dangerous, leading to heatstroke, dehydration, and other health problems.
Pro Tip: Staying Safe During Heatwaves
Stay Hydrated: Drink plenty of fluids, even if you don’t feel thirsty.
Seek Shade: Limit outdoor activities during peak heat hours.
Wear Light Clothing: Opt for loose-fitting, light-colored clothing.
Monitor Vulnerable Individuals: Check on elderly neighbors and family members.
Frequently Asked Questions

- What is the IMD?
- The IMD stands for India Meteorological Department, the national meteorological agency of India.
- What is ENSO?
- ENSO stands for El Niño-Southern Oscillation, a climate pattern in the tropical Pacific Ocean that can influence weather patterns worldwide.
