September weather forecastSrivaikuntam, India

Weather in September

The last month of the rainy (monsoon) season, September, is another tropical month in Srivaikuntam, India, with an average temperature varying between 33.4°C (92.1°F) and 24.9°C (76.8°F).

Temperature

Srivaikuntam experiences a subtle adjustment in high-temperatures to a still hot 33.4°C (92.1°F) with the onset of September, maintaining near parity with August's 33.4°C (92.1°F). Throughout September, the temperature falls to an average low of 24.9°C (76.8°F).

Heat index

The average heat index in September is estimated at an extremely hot 42°C (107.6°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Exercise precautions and adapt sun safety practices. Defence against skin and eye affliction is paramount. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
