Weather in September
Temperature
September's beginning signals an average high-temperature of a warm 85.6°F (29.8°C), barely different from August's 90.7°F (32.6°C). An average low-temperature of 65.5°F (18.6°C) is common in Mathiston during the nights of September.Heat index
The heat index value for September is computed to be a sweltering 95°F (35°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
