Weather in September
Temperature
September brings a slight decrease in the average high-temperature, shifting from 93°F (33.9°C) in August to a still hot 87.3°F (30.7°C). Frenchport's temperature lowers to a mean of 65.8°F (18.8°C) during the nights in September.Heat index
Throughout September, the heat index is computed to be a very hot 98.6°F (37°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
