Weather in September
Temperature
The average high-temperature during September is a still hot 88.3°F (31.3°C), almost matching the conditions of the preceding month. Southfort reports an average nighttime low-temperature of 75.6°F (24.2°C) in September.Heat index
The heat index in September is calculated to be a scorching 105.8°F (41°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. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
