Weather in September
Temperature
A minor decrease in the average high-temperature is observed during September, shifting from a torrid 95.2°F (35.1°C) in August to a hot 88.9°F (31.6°C). Stonewall, during the month of September, experiences an average low-temperature of 68.2°F (20.1°C).Heat index
In September, the heat index is evaluated at a fiery hot 102.2°F (39°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 extremely significant for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
