Weather in September
Temperature
September's climate shows a minor adjustment in average high-temperatures to a still tropical 87.1°F (30.6°C) from August's 91°F (32.8°C). In Deatsville, the expected average low-temperature for September is a refreshing 67.3°F (19.6°C).Heat index
During September, the heat index is calculated to be a sweltering 98.6°F (37°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
