Weather in September
Temperature
September's advent denotes a minor fluctuation in the average high-temperature to a still hot 31.6°C (88.9°F) from August's 31.3°C (88.3°F). The average nighttime temperature lowers to a moderately hot 23.5°C (74.3°F) throughout September.Heat index
In September, the average heat index is estimated at a blisteringly hot 40°C (104°F). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
