Chennai: The Regional Meteorological Centre (RMC) has issued a warning for a rise in temperatures of 2 to 3 degrees Celsius across Tamil Nadu over the next four days. According to the weather department, the heatwave is being caused by light to moderate easterly and northeasterly winds in the lower troposphere. The maximum temperature is expected to increase in northern coastal districts, including Chennai, Kancheepuram, Chengalpattu, and Tiruvallur.
The RMC has linked the rise in temperatures to the ongoing La Nina effect, which delayed the retreat of the northeast monsoon and contributed to a weaker winter season. The lack of cloud formation and reduced moisture levels over the sea have further exacerbated the temperature increase in both coastal and interior regions of the state.

Moderate heatwave expected
Despite the current heat surge, experts predict no significant rise in summer temperatures for the long term. Temperatures are expected to remain around 38-39°C, similar to previous years. However, some interior districts, such as Karur, Erode, and Salem, experienced a rise in temperatures in February, and this trend may continue, with temperatures in these areas likely increasing by 1 or 2 degrees Celsius above normal levels.
The weather department has also warned of mist formation during the early morning hours due to changing wind patterns. This could reduce visibility and affect morning travel in certain areas.
Health advisory issued to protect public
In response to the rising temperatures, the Directorate of Public Health and Preventive Medicine has issued a health advisory urging the public to take precautions. The advisory recommends staying hydrated by drinking homemade drinks like lemon water, buttermilk, lassi, and fruit juices with a pinch of salt. It also suggests consuming fruits and vegetables that are rich in water content.
The health department advises the public to stay indoors in cool, well-ventilated areas, keep windows and curtains closed during the day to block heat, and only open them at night for ventilation. It is also recommended to schedule outdoor activities during cooler hours and avoid direct sunlight, alcohol, caffeinated drinks, carbonated beverages, and high-protein foods.
The advisory highlights the importance of extra precautions for vulnerable groups, including infants, young children, pregnant women, and individuals with heart conditions. People working outdoors are advised to limit sun exposure, avoid strenuous activities during peak heat hours, take frequent breaks in shaded areas, and drink water every 20 minutes.
Avoiding risks for children and pets
The DPH has also issued a warning not to leave children or pets inside parked vehicles, as temperatures inside can rise to dangerously high levels. Elderly individuals and those who are unwell should be monitored regularly, and those living alone should have someone check on them.
The public is advised to avoid stepping out between 12:00 pm and 3:00 pm and seek medical attention if experiencing dizziness, headaches, or heat-related stress. With the heat expected to rise over the coming days, residents are urged to stay vigilant and take appropriate measures to stay safe.
