Weather in September

September, the first month of the autumn in Andrews, is still a tropical month, with an average temperature varying between 72.9°F (22.7°C) and 87.3°F (30.7°C).

Temperature

September's average high-temperature stands at a still hot 87.3°F (30.7°C), showing little deviation from August's 90.3°F (32.4°C). Andrews's nighttime temperature during September is consistently averaged at an agreeable 72.9°F (22.7°C).

Heat index

September's mean heat index is evaluated at a torrid 102.2°F (39°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposure to the sun directly might heighten 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 influence one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
