Weather in September

September arrives with subtle hints of autumn amidst the prevailing summer heat. A noticeable descent in both maximum and minimum temperatures is recorded compared to August. Rainfall measures drop significantly to about 2.44" (62mm), potentially alleviating some of the succulent late-summer humidity. Furthermore, daylight hours reduce, gradually peeling away the extended summer days. An absence of snow ensures the summer warmth lingers in the passing days of September, despite the steadily closing in autumn.

Temperature

Pineville starts September with an average high-temperature of a still tropical 88°F (31.1°C), a minor shift from August's 92.8°F (33.8°C). In September, the nighttime temperature lowers to an average of 68°F (20°C).

Heat index

In September, the heat index is evaluated at a scorching 104°F (40°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 are especially crucial for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
