Weather in September

September, the first month of the autumn in Slagle, is also a hot month, with an average temperature fluctuating between 68.7°F (20.4°C) and 88.7°F (31.5°C).

Temperature

The introduction of September sees an average high-temperature of a still tropical 88.7°F (31.5°C), hardly deviating from August. An average low-temperature of 68.7°F (20.4°C) is common during the nights of September.

Heat index

In September, the heat index is evaluated at a blisteringly hot 105.8°F (41°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. 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 highly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Note: The daily high UV index of 6 in September translates into this advice:
Fend off overexposure. Sun protection is vital. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses. Take careful note! The UV radiation of the Sun can be nearly doubled by snow reflection.
