No heatwave in April: Multiple weather systems likely to cool down India
The relief feels especially welcome after the rising nighttime heat, humidity, and power strain experienced in recent summers.
There is some good news for millions of Indians tired of the early summer heat since early March.
There will be no heatwaves across most of the country until the end of April as the frequent spells of rain and clouds will keep temperatures comfortably below normal in large parts of north and central India.
Temperatures in northwest and central regions are likely to stay 2C-5C below normal at least until April 20.
WHY IS INDIA'S WEATHER SUDDENLY COOL?
The reason behind this spell of cold respite is western disturbances.
Western disturbances are rain-bearing weather systems that travel from the Mediterranean Sea and bring clouds, showers and thunderstorms to northern India.
Right now, multiple such systems are active, as confirmed by the India Meteorological Department (IMD) on March 29.
These weather systems are causing widespread light to moderate rainfall, thunderstorms, and gusty winds across Punjab, Haryana, Delhi, Uttar Pradesh, Rajasthan and the Himalayan states.
This is a sharp turnaround from early March's weather which saw unseasonally hot days, marking an early end to winters. March 2026 also shattered records, with Delhi hitting its hottest first week in 15 years and temperatures 4C-12 C above normal in many places.
Parts of Gujarat and Rajasthan even saw early heatwave alerts, with the mercury crossing 40C.
IMD’s seasonal outlook had warned of more heatwave days than usual between March and May 2026 because of overall warmer trends. But these active western disturbances have changed the short-term picture.
The weather department's extended range outlook for the next two weeks, till April 9, clearly states that heat wave conditions are unlikely. It further notes that maximum temperatures will stay normal to below normal across most of the country.
CAN DELAYED HEATWAVES SAVE ENERGY?
There is also the optimistic scenario where the delayed heatwave will help India save on its energy bills.
When days stay 2C-5C cooler, people need less air-conditioning and fans. In cities like Delhi and Mumbai, even small drops in temperature can cut peak power demand noticeably, helping avoid those dreaded summer blackouts.
Many residents in Noida and Gurgaon have already noticed they haven’t switched on their ACs yet, even as March ends.
The relief feels especially welcome after the rising nighttime heat, humidity, and power strain experienced in recent summers.
Of course, the south may still see hotter days, and longer-term summer trends point to above-normal heat later. But for now, India is protected by a fateful weather system.
