Weather in September
Temperature
The move into September indicates a slight reduction in the average high-temperature, down from August's hot 94.8°F (34.9°C) to a still tropical 88.5°F (31.4°C). Throughout the month of September, Overton sees a steady low-temperature average of 68°F (20°C).Heat index
In September, the heat index is appraised at a torrid 100.4°F (38°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
