Weather in September
Temperature
Forest Home, Alabama, ushers in September with an average high-temperature of a still hot 87.1°F (30.6°C), showing a close resemblance to the previous month. In the month of September, Forest Home experiences an average low-temperature of 67.8°F (19.9°C).Heat index
For most parts of September, the heat index is evaluated at a sweltering 100.4°F (38°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Heat index determinations are made taking into account the shade and light air movements. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
