Weather in September
Temperature
The advent of September signifies a minor shift to an average high-temperature of a still tropical 87.3°F (30.7°C), aligning closely with August. Blountstown's September nights cool down to an average low-temperature of 70.2°F (21.2°C).Heat index
For September, the heat index is evaluated at a very hot 102.2°F (39°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. 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. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
