Weather in September
Temperature
Upon the beginning of September, Girard's high-temperatures register at a still tropical 87.1°F (30.6°C), closely mirroring the preceding month. Throughout September, an average low-temperature of 68.2°F (20.1°C) is experienced.Heat index
The average heat index in September is appraised at a torrid 98.6°F (37°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly critical for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period.
