The India Meteorological Department (IMD) has issued its summer forecast, which predicts intensified heat waves and elevated temperatures across India. While the summer forecast does not receive as much attention as monsoon forecasts, its impact on daily life and livelihoods is apparent. With rising temperatures and increased heatwave days, the country must prepare for a lengthy and hot summer season. The IMD’s findings show that daytime and nighttime temperatures would be higher than typical, notably in northwest and eastern India, posing challenges to public health, infrastructure, and agricultural productivity.
Increased Heat Wave Days and Rising Temperatures
According to the IMD, India usually has four to seven heatwave days between April and June. A heatwave is announced when temperatures rise to 45 degrees Celsius or higher, with severe heat waves occurring at 47 degrees Celsius or higher. Alternatively, if maximum temperatures in the plains surpass 40 degrees Celsius and are 4.5 to 6.4 degrees Celsius above average, the IMD considers it a heatwave.
According to IMD’s April forecast, most parts of the country will experience heatwaves and elevated temperatures across India, with only a few isolated places in northwest and northeast India anticipated to have normal or below-normal minimum temperatures.

Mitigation Strategies and Estimated Rainfall Relief
The IMD has recommended implementing heat action plans and other preventive measures to remove the negative effect of the heat. Vulnerable groups, like the elderly, children, and people with pre-existing health issues, may need extra care tending to the increased risk of heat-related illnesses like heat exhaustion and heatstroke. Authorities are encouraged to establish cooling centres, issue heat advisories, and devise methods to fight urban heat island impacts.
Apart from the grim temperature forecast, there is some relief in sight. IMD predicts normal to above-normal rainfall in April for northwest, peninsular, and northeast India, which may help counteract some of the extreme heat. This will be a much-needed respite after a dry March, which recorded a 32.6% national deficit. Additionally, ENSO (El Niño-Southern Oscillation) conditions are changing to a neutral phase, which could lead to more stable weather.
Conclusion
The IMD’s summer prediction focuses on the growing influence of climate change and regional atmospheric variability on India’s weather patterns. With the possibility of prolonged heat waves and elevated temperatures across India, preparatory measures will be critical for limiting the effects on public health, agriculture, and infrastructure. While regular rainfall in April may provide some relief, the general pattern suggests India is about to see one of its hottest summers. Proactive efforts, such as implementing heat action plans and enhanced resource management, will improve resilience to extreme weather events.
