Weather in September
Temperature
The transition into September subtly indicates a reduction in the average high-temperature, down to a hot 88.5°F (31.4°C) from August's very hot 96.3°F (35.7°C). During September, Leroy records a consistent average nighttime temperature of 70.5°F (21.4°C).Heat index
For September, the heat index is appraised at a very hot 98.6°F (37°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
