Weather in September
Temperature
September's onset records a minor alteration in the average high-temperature to a moderately hot 85.8°F (29.9°C) from August's 90.7°F (32.6°C). During September, Henslee Heights records an average temperature of 66.2°F (19°C) at night.Heat index
September's average heat index is calculated to be a fiery hot 95°F (35°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
