Weather in September
Temperature
With September's onset, the weather reveals a slight temperature decrease, transitioning from a hot 86.9°F (30.5°C) in August to a warm 81.5°F (27.5°C). Deep Run records an average low-temperature of 65.3°F (18.5°C) throughout the month of September.Heat index
The heat index for September is computed to be a tropical 87.8°F (31°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. 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.
