The average heat index in September is calculated to be a torrid 36°C (96.8°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.

Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
