Weather in September
Temperature
September's weather displays an average high-temperature of a still hot 32.6°C (90.7°F), slightly varied from August's 31.8°C (89.2°F). An average low-temperature of 25.7°C (78.3°F) is recorded in the month of September.Heat index
September's average heat index is computed to be a blistering 44°C (111.2°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.Heat index determinations are made taking into account the shade and light air movements. 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 'feels like' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. 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. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
