Weather in September
Temperature
The commencement of September brings an average high-temperature of a still hot 86°F (30°C), marking an inconsequential divergence from August. Abbeville reports an average low-temperature of 71.8°F (22.1°C) during the nights of September.Heat index
September's mean heat index is evaluated at a sweltering 98.6°F (37°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index determinations are made taking into account the shade and light air movements. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
