IMD Warns of Severe Heatwave in North India in 2026, More ‘Loo’ Days Expected Across Key States

New Delhi, India | April 21, 2026

The India Meteorological Department has issued a strong warning for an intense summer in 2026, predicting that large parts of North India and several other regions will experience above-normal heatwave days during the April–June period.

According to IMD Director General Mrutyunjay Mohapatra, temperatures in some regions are expected to exceed 40°C, which is typical for the season but may occur more frequently this year.

Northern Plains Likely to See Severe Heatwave Conditions

The IMD said that northern plains—including states such as Haryana, Uttar Pradesh, Bihar, and Jharkhand—are likely to face prolonged and intense heatwave conditions, commonly referred to as “loo.”

Eastern and coastal regions are also expected to be impacted. Areas including southern West Bengal, Odisha, Andhra Pradesh, Chhattisgarh, and Telangana may witness heatwave conditions, along with parts of Rajasthan, Gujarat, Madhya Pradesh, and northern Maharashtra.

The weather agency noted that while high temperatures are common between April and June, year-to-year variations could make this season significantly harsher than usual.

Early Forecasting and Monitoring in Place

IMD has been issuing seasonal and extended forecasts to help authorities and the public prepare in advance. The agency released its first heatwave outlook in late February for March–May and later updated it at the end of March for April–June.

Weekly extended forecasts covering the next four weeks are released every Thursday, while district-level warnings for the next seven days are issued daily during peak summer.

Focus on Public Awareness and Vulnerable Groups

To ensure timely communication, IMD has adopted multiple outreach strategies, particularly targeting vulnerable populations such as outdoor workers, laborers, and street vendors.

Authorities have created WhatsApp groups to share real-time temperature updates and advisories. Public display boards are also being installed in high-footfall areas to spread awareness about heat risks and preventive measures.

Additionally, alerts are being disseminated through the Common Alert Protocol system of the National Disaster Management Authority, enabling mobile users across the country to receive warnings directly.

Challenges in Reaching All Populations

Despite digital outreach, officials acknowledged that certain populations still lack access to mobile alerts. IMD emphasized the need for traditional and innovative communication methods to ensure that critical information reaches every section of society.

Rising Heat Risks

The warning underscores growing concerns about extreme weather patterns in India, with heatwaves becoming more frequent and severe. Experts say preparedness, awareness, and early warning systems will be key to minimizing health and economic impacts.
