The heatwave poses significant risks of heat-related illnesses, particularly for vulnerable groups such as children, senior citizens, and individuals with pre-existing health conditions. High temperatures combined with elevated humidity levels are expected to cause discomfort, especially in coastal areas. Residents in affected districts are advised to avoid prolonged sun exposure and take precautions to stay hydrated. The humid conditions in Chennai and other coastal regions may exacerbate the feeling of heat, even in areas not officially recording heatwave temperatures.
