The average heat index in September is estimated at a fiery hot 36°C (96.8°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high.

Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. 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 especially vital to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. 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. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
