Weather in September

September brings the commencement of the fall season, signaling a certain cooling. The noticeable descent in temperature ensures a pleasant environment, as does the negligible wind gust speed of 8.6mph (13.8km/h). The parade of rainfall starts to slack, implying the beginning of the drier part of the year. A declining UV index and daylight hours clearly mark the transition from summer to fall. The moderately high visibility in September makes it conducive for exploratory walks and picnics.

Temperature

The average high-temperature during September is a still tropical 88.7°F (31.5°C), almost matching the conditions of the preceding month. During September, Leesville witnesses a consistent average low-temperature of 68.7°F (20.4°C).

Heat index

September's mean heat index is estimated at an extremely hot 105.8°F (41°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
