Temperature

September notes an average high-temperature of a still tropical 31.3°C (88.3°F), aligning with the previous month's conditions. In Simhachalam, September nights experience a modest descent in temperature from daily peaks, cooling down to an average of 26.9°C (80.4°F).

Heat index

In September, the heat index is estimated at an extremely hot 40°C (104°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Note: In September, a daily UV index of 7 turns into the following recommendations:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
