Weather in September
Temperature
The commencement of September brings an average high-temperature of a still hot 32.2°C (90°F), marking an inconsequential divergence from August. Throughout September, an average low-temperature of 22.8°C (73°F) is expected.Heat index
In September, the heat index is evaluated at a burning hot 47°C (116.6°F). Observe: Heat exhaustion and heat cramps are probable. Heatstroke is on the horizon with prolonged exertion.The heat index's values are generally associated with conditions in shade and light breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Experience reduced UV exposure by about half when donning a wide-brim hat.
