IMD Warning: 12 Extreme Heatwave Days Expected in Northwest India – Stay Safe!

India is set to experience an exceptionally hot summer, with the IMD predicting up to 12 heatwave days in Northwest India—almost double the usual number. Typically, the region faces around 5-6 heatwave days, but this year, temperatures are expected to be slightly above normal, particularly in West and Central India. While not every day will be extreme, IMD will provide regular updates for more accurate forecasts. A heatwave is declared when temperatures in the plains reach 40°C or rise 5°C above normal.

From March to May 2025, most parts of India will see higher-than-average temperatures, except some southern and northeastern areas, which may have near-normal weather. North India, including Delhi, will experience a 1-2°C temperature rise in the coming days, though northwesterly winds from Rajasthan may briefly cool temperatures by 3-4°C. These winds, moving at 20-30 km/h, will create dry and dusty conditions in Punjab, Haryana, and Rajasthan. While it’s uncertain if 2025 will break last year’s heat records, staying hydrated and taking precautions will be essential to cope with the intense summer ahead.

IMD Warning: 12 Extreme Heatwave Days Expected in Northwest India – Stay Safe!

The India Meteorological Department (IMD) has issued a stark warning: Northwest India is set to endure an unusually harsh summer, with heatwave conditions expected to last nearly twice as long as usual. Areas that typically experience five to six days of extreme heat annually could face 10 to 12 heatwave days this season. This alarming forecast underscores the increasing intensity of summer weather patterns, urging residents and authorities to prepare for prolonged periods of dangerously high temperatures.

Above-Normal Temperatures Expected Nationwide

According to IMD scientist Soma Sen Roy, while temperatures across West and Central India are predicted to be slightly above normal, this does not mean relentless, unbearable heat every day. “This is a seasonal outlook, not a daily forecast,” she clarified. The IMD will release regular updates as summer progresses, providing more precise short-term predictions. For now, the broader trend indicates a hotter-than-average season for much of the country.

Defining a Heatwave: When Does the Alarm Sound?

A heatwave is officially declared in India’s plains when temperatures reach at least 40°C or rise 5°C above the region’s historical average. In hilly or coastal areas, the threshold is slightly lower, at 30°C or 4.5°C above normal. These criteria help authorities issue timely warnings, allowing communities to take protective measures against heat-related health risks.

Regional Breakdown: Who Will Feel the Heat?

From March to May 2025, most of India—particularly the Northwest, Central, and Western states—is likely to experience above-average temperatures. However, the southernmost parts of the country (including Tamil Nadu and Kerala) and some areas in the Northeast (such as Assam and Meghalaya) may experience near-normal or slightly cooler conditions. This regional variation highlights India’s diverse climate, where geography plays a key role in moderating weather extremes.

North India’s Temperature Roller Coaster

In the short term, North India, including Delhi, Punjab, Haryana, and Rajasthan, is expected to experience a gradual temperature rise of 1–2°C over the next few days. However, relief may come as strong northwesterly winds from Rajasthan sweep across the region. These winds, moving at speeds of 20–30 km/h, could temporarily lower temperatures by 3–4°C but will also bring dry, dusty conditions. Residents in affected areas should prepare for reduced visibility and potential respiratory discomfort, especially during peak wind activity.

Will 2025 Break Previous Heat Records

While it’s too early to determine whether 2025 will surpass 2024 as India’s hottest year on record, the IMD’s projections leave little doubt: this summer will be exceptionally challenging. Urban centers, where concrete landscapes trap heat, are particularly vulnerable. Cities like Delhi, Jaipur, and Lucknow, which already endure oppressive summers, could face even more extreme conditions this year.

Staying Safe in the Swelter

The IMD and health authorities are urging people to take necessary precautions during peak heat hours (10 AM to 4 PM). Some key safety measures include:

• Hydration: Drink water regularly, even if not feeling thirsty. Avoid alcohol and caffeine, as they can worsen dehydration.
• Clothing: Wear loose, light-colored outfits made from breathable fabrics like cotton.
• Indoor Safety: Use curtains or shades to block sunlight. Fans and coolers help, but air-conditioned spaces are ideal during extreme heat.
• Protecting Vulnerable Groups: Children, the elderly, and those with chronic illnesses should limit outdoor exposure. Community efforts to check on at-risk individuals are encouraged.
• Recognizing Heatstroke Symptoms: Watch for signs like dizziness, headaches, rapid heartbeat, and confusion—these require immediate medical attention.

The Bigger Picture: Climate Change and Heat Patterns

While seasonal variations in temperature are normal, the increasing frequency and intensity of heatwaves align with global climate trends. Studies link rising temperatures to human-driven climate change, underscoring the need for long-term strategies such as urban green spaces, heat-resistant infrastructure, and public awareness campaigns. In the short term, adaptive measures remain crucial to mitigating health and economic impacts.

Final Thoughts

As Northwest India braces for a grueling summer, the IMD’s warnings serve as a critical reminder of the immediate dangers posed by rising temperatures. By staying informed, following advisories, and adopting preventive measures, individuals and communities can navigate the heat more safely. While the months ahead will be challenging, preparedness and collective action can significantly reduce risks and save lives.

Stay updated with local weather forecasts, follow official guidelines, and prioritize health—this summer, vigilance is the key to resilience.
