September weather forecast
Pineville, LA

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

An average high-temperature of a still tropical 88°F (31.1°C) marks September, exhibiting a close resemblance to the conditions in August. September nights cool down to an average low-temperature of 68°F (20°C).

Heat index

For September, the heat index is estimated at a scorching 104°F (40°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat. Heads up! The UV radiation from the Sun can almost be doubled by snow reflection.
