Will Summer Of 2026 Be Hotter Than The Great Heatwave Of 2024 When Temperatures Crossed 50°C?

Last Updated:March 10, 2026, 18:26 IST

February 2026 was recorded as one of the warmest since 1901, with temperatures in many regions feeling like late March. What next? What precautions to take? News18 explains

The summer of 2026 is likely to be a “scorching preview" of the record-breaking heat seen in 2024, with some experts warning it could even mirror or surpass those extreme conditions.

The India Meteorological Department (IMD) has already issued early alerts for above-normal maximum temperatures across most of India from March to May 2026.

WHY THE QUESTION

February 2026 was recorded as one of the warmest since 1901, with temperatures in many regions feeling like late March.

A transition from La Niña to El Niño conditions is expected by mid-2026. Historically, El Niño events in India are linked to intense heatwaves and potential monsoon irregularities.

2026 is forecast to be the fourth consecutive year with average global temperatures rising by at least above pre-industrial levels.

WHICH AREAS MAY BE WORST HIT?

The IMD predicts an increased number of heatwave days (3 to 15 days above normal) in these key regions:

North & Northwest: Rajasthan, Delhi, Punjab, Haryana, and Uttar Pradesh

East & Central: Odisha, West Bengal, Bihar, Jharkhand, and Chhattisgarh

South & West: Gujarat, Maharashtra, Telangana, Andhra Pradesh, and North Interior Karnataka.

HOW YOU CAN PROTECT YOURSELF FROM HEAT

To protect yourself from heat exhaustion and heatstroke, you must focus on three pillars: hydration, cooling, and smart scheduling. Heat exhaustion is a moderate illness that can progress to heatstroke, which is a life-threatening medical emergency.

Stay Hydrated: Sip water throughout the day, even if you do not feel thirsty. Replenish electrolytes: If you are sweating heavily, use sports drinks or oral rehydration solutions to replace lost salts. Limit alcohol, caffeine (tea/coffee), and sugary sodas, as these can worsen dehydration. Incorporate fruits and vegetables with high water content, such as watermelon, cucumber, and oranges.

Stay Cool and Dress Appropriately: Choose lightweight, loose-fitting, and light-coloured clothing made from breathable fabrics like cotton or linen. Wear a wide-brimmed hat and sunglasses. Apply broad-spectrum sunscreen (at least SPF 15-30) and reapply every two hours, as sunburn hinders your body’s ability to cool itself. Take cool showers or baths, or use damp cloths on your neck, wrists, and forehead.

Keep blinds or curtains closed during the day to block direct sunlight. Use air conditioning or visit public cooling centres like libraries or malls if your home is too hot.

Stay indoors during the hottest parts of the day, typically between 10:00 AM and 4:00 PM. Perform strenuous activities in the early morning or late evening when it is cooler. Give your body 1–2 weeks to adjust to hot weather before engaging in intense physical activity. Rest often in shaded or air-conditioned areas during outdoor tasks.

HOW TO PROTECT YOUR PHONE AND APPLIANCES?

To prevent the “AC fires" and “phone overheating" seen during the 2024 heatwaves, experts recommend:

Air Conditioners

Avoid running units continuously for more than 5 hours.

Maintain a steady temperature of 24°Celsius rather than 16-18°Celsius to reduce compressor pressure.

Ensure coils are cleaned of dirt/dust to prevent condenser overheating.

Smartphones & Gadgets

Avoid high-processing tasks (gaming, video editing) in high ambient heat.

Do not use the phone while it is charging, as this creates dual heat stress on the battery.

Keep devices out of direct sunlight and away from car dashboards.

THE GREAT HEATWAVE (APRIL–JUNE 2024)

India experienced its longest heatwave since 2010, with temperatures in several regions hovering around 50°Celsius for weeks.

RECORD-BREAKING PEAKS

Mungeshpur, Delhi: Recorded a staggering 52.3°Celsius on May 29, though later attributed to a possible sensor error.

Phalodi, Rajasthan: Hit 51°Celsius

Sirsa, Haryana: Reached 50.3°Celsius.

HEALTH & HUMAN COST

Official reports cited 143 deaths and over 41,000 heatstroke cases, though independent studies estimated the toll could be as high as 733 deaths.

At least 33 polling officials died from heatstroke during the final phase of the Lok Sabha elections in Uttar Pradesh due to a lack of cooling facilities.

Delhi recorded its warmest night ever with a minimum temperature of 35.2 degrees Celsius.

TECHNOLOGICAL & INFRASTRUCTURE STRAIN

The extreme heat led to a surge in appliance and device failures:

High ambient temperatures caused air conditioners to run continuously, leading to overloaded circuits, melting internal wiring, and fires.

High temperatures caused smartphone batteries to swell or catch fire, especially when used in direct sunlight or for high-processing tasks.

New Delhi faced a severe water shortage as river levels dropped and consumption spiked, requiring emergency water tankers.

THE CATASTROPHIC FLOODS THAT FOLLOWED IN AUGUST-SEPTEMBER 2024

As the monsoon progressed, the “heat trap" gave way to extreme precipitation events:

Gujarat (Late August): Received 23% of its seasonal rainfall in just 72 hours, causing massive flooding that affected over 8 million people and claimed 61 lives.

Andhra Pradesh & Telangana (Early September): Vijayawada saw one of its worst floods in history after 290 mm of rain fell in a single day, leading to 66 deaths.

Northern India (Mid-September): Flooding in the Yamuna Basin displaced millions across Uttar Pradesh, Madhya Pradesh, and Rajasthan.
