North Tamil Nadu braces for hotter summer as IMD flags heatwave days

North Tamil Nadu and coastal parts of the state may have to brace for a hotter summer as the India Meteorological Department forecasts above-normal heatwave days from March to May. Heatwaves are declared when the maximum temperature crosses 40°C in plains and 30°C in hilly regions, a threshold that could be breached more frequently this season as temperatures rise.

Officials say weekly and extended-range forecasts, along with impact-based advisories, will be issued to guide public health responses, water-supply planning, and power demand management. The Regional Meteorological Centre emphasised that these updates will help authorities and communities prepare for heat-related risks, including heat illness and water scarcity.

March is expected to bring a brief relief in some pockets, but the first month of summer will likely see above-normal minimum temperatures across most areas, according to IMD director-general Mohapatra. The agency cautions that higher nighttime temperatures can complicate cooling and health conditions.

Separately, experts note that the heat trend is not limited to Tamil Nadu. Across much of India, a harsher summer with more heatwave days is anticipated through May 2026, with energy grids bracing for higher demand and vulnerable populations urged to plan ahead.

Public health and civic authorities say people should stay hydrated, avoid outdoor work during peak sun, and keep seniors and children in shade. Businesses, transport, and schools may adjust schedules in response to forecasts. Farmers may face stress on irrigation and crop planning as water resources come under pressure.

Residents are advised to monitor official forecasts and heed advisories, especially during heatwave alerts. Small acts—drinking water, wearing light clothing, and seeking air-conditioned spaces—can make a difference.
