The onset of September marks an average high-temperature of a still hot 32.8°C (91°F), hardly differing from August's 33.7°C (92.7°F). In September, the average low-temperature is a moderately hot 23.5°C (74.3°F).

Heat index

Heat index readings emphasize conditions of light breezes and shaded spots. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. 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. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
