Weather in September
Temperature
The onset of September is marked by a minor decrease in temperature, transitioning from a sweltering 96.1°F (35.6°C) in August to a tropical 90.1°F (32.3°C). Mathis records an average low-temperature of 75.2°F (24°C) throughout the month of September.Heat index
For most parts of September, the heat index is computed to be an extremely hot 105.8°F (41°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
