Weather in September
Temperature
Smiths Mill, Georgia, experiences a subtle adjustment in high-temperatures to a warm 85.3°F (29.6°C) with the onset of September, maintaining near parity with August's 89.8°F (32.1°C). September nights observe an average temperature dip to a comfortable 66°F (18.9°C).Heat index
The heat index in September is calculated to be a torrid 95°F (35°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Understanding the heat index involves considering values for shaded locales with light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
