Weather in September
Temperature
The arrival of September correlates with a minor temperature reduction, down from August's sweltering 95.5°F (35.3°C) to a hot 88.3°F (31.3°C). During September, Groesbeck witnesses a consistent average low-temperature of 69.4°F (20.8°C).Heat index
September's mean heat index is computed to be a sweltering 100.4°F (38°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.For clarity, heat index numbers account for light winds and areas under shade. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

The average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the average person.Note: In September, the maximum UV index of 6 suggests this advice:
Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Enhance your sun protection with tightly woven, yet airy clothing.
