Weather in September
Temperature
The commencement of September indicates a gentle shift in the average high-temperature, receding from August's very hot 95.5°F (35.3°C) to a hot 86.9°F (30.5°C). Throughout the month of September, Millsap sees a steady low-temperature average of 68.4°F (20.2°C).Heat index
The heat index value during September is calculated to be a fiery hot 95°F (35°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
