Weather in September
Temperature
The onset of September manifests an average high-temperature of a still hot 87.6°F (30.9°C), demonstrating a minor variation from the preceding month. Sweetwater maintains a near steady average temperature of 79.7°F (26.5°C) during the nights of September, demonstrating little drop from daytime highs.Heat index
September's heat index is appraised at a fiery hot 100.4°F (38°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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 the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time.
