Heat Wave 2025: India to Experience Above-Average Temperatures from March to May

KKN Gurugram Desk | India is bracing itself for a hotter summer in 2025, with the India Meteorological Department (IMD) predicting that the temperature will be above-average across much of the country between March and May. This forecast indicates that the heatwave and other extreme weather events will be more intense than usual. While some parts of peninsular India and the Northeast may experience relatively cooler temperatures, the majority of the nation will face intense heat this summer.

Heatwave Forecast for March to May 2025

According to the IMD, the heatwave in India is expected to be above normal from March to May. The maximum temperatures across most parts of the country will exceed the seasonal averages. The southern peninsular region and a few areas in the Northeast are expected to see relatively lower temperatures. However, the rest of India will experience higher-than-usual heat during this period.

What Does the Forecast Say?

1. Above-Average Temperatures Across Most Parts:
   The IMD forecast indicates that the maximum monthly temperatures from March to May will be higher than usual in most parts of the country. Exceptions will be the southern parts of peninsular India and some regions in the Northeast, where temperatures may remain closer to normal.

2. Higher Minimum Temperatures Expected:
   Apart from the maximum temperatures, the minimum monthly temperatures are also expected to be above-average across most of India. The only exceptions to this forecast will be some parts of northwestern India and the southwest peninsular region.

3. Heatwave Events Likely to Increase:
   The IMD predicts that heatwaves will be more frequent and intense this year. The northeastern states, parts of far northern India, and some regions in the southwest will be largely unaffected by extreme heatwaves. However, for the rest of the country, heatwaves are likely to occur more frequently, and the intensity of the heat is expected to be significantly higher.

Understanding the Heatwave Phenomenon

A heatwave occurs when the temperature of a particular region rises significantly above the normal for an extended period. According to the IMD, heatwaves are declared when the maximum temperature reaches 40°C or more in plains, 37°C in coastal areas, or 30°C in hilly regions for more than two consecutive days. This temperature increase is expected to affect large swaths of India during the upcoming summer.

Heatwaves can have severe consequences on both the health of individuals and the environment. The continuous exposure to extreme temperatures increases the risk of heatstroke, dehydration, and other heat-related illnesses. Additionally, agriculture may also be adversely impacted, with crops suffering from excessive heat.

Regional Variations in the 2025 Heatwave

While most of India will experience higher-than-average temperatures, certain regions will not be as affected by the heat. Here’s a breakdown of the regions expected to see different temperature patterns:

• Southern Peninsular India:
  The southern states of India, including Tamil Nadu, Kerala, Karnataka, and parts of Andhra Pradesh, are expected to see relatively cooler temperatures compared to the rest of the country. This is due to the geographical location and the moderating effects of the sea.

• Northeastern India:
  The Northeast is another region that may witness cooler weather compared to other areas of the country. States like Assam, Meghalaya, and Nagaland are expected to experience normal or slightly lower temperatures during the summer months.

• Northern and Northwestern India:
  The states in the north and northwest, including Rajasthan, Delhi, and Punjab, will experience higher-than-normal temperatures. These areas are often the hardest hit by heatwaves due to their arid and semi-arid landscapes, which absorb heat and cause extreme temperature fluctuations.

Impact of Heatwaves on Public Health and Environment

Heatwaves are not just uncomfortable; they can also be life-threatening. The IMD’s forecast for 2025 suggests that heat stress could increase the incidence of heatstroke and other heat-related health conditions. Vulnerable populations, such as elderly people, children, and those with pre-existing health conditions, may be at higher risk.

The rise in temperature can also strain water resources. As temperatures soar, there will likely be an increase in water consumption, which could lead to a strain on already stressed water supply systems in many parts of India.

Additionally, agriculture could face severe challenges. Crops that are sensitive to heat, such as wheat, pulses, and maize, may see a reduction in yields due to the higher-than-average temperatures.

The Role of the India Meteorological Department

Since 2016, the India Meteorological Department has been providing seasonal forecasts for both the winter and summer seasons. The IMD has consistently improved its forecasting models and has made significant strides in enhancing the accuracy of its predictions.

One of the key improvements is the use of the multi-model ensemble (MME) forecasting system, which incorporates data from multiple weather models. This helps improve the reliability of weather forecasts and allows the IMD to predict extreme weather events with greater precision.

What Can People Expect in the Coming Months?

With the heatwave predictions, people in many parts of India will need to take precautionary measures to cope with the upcoming summer heat. Some important tips include:

• Stay Hydrated: Drink plenty of water throughout the day to avoid dehydration. Avoid alcohol and caffeinated drinks, which can lead to water loss.

• Use Sunscreen: To protect your skin from harmful UV rays, use sunscreen with a high SPF. Wearing hats and light-colored clothing can also help minimize sun exposure.

• Avoid Peak Sun Hours: Try to stay indoors during the hottest part of the day, typically between 11 AM and 4 PM.

• Be Aware of Heat-related Illnesses: Learn about the signs of heatstroke and heat exhaustion, and seek medical help immediately if you experience symptoms such as dizziness, nausea, or excessive sweating.

 

The Heatwave 2025 is expected to be a challenging season for many parts of India, with above-normal temperatures likely to affect most of the country. While some regions, such as the southern peninsular and northeastern India, may see relatively cooler weather, the majority of the nation will experience intense heat from March to May.
