Weather in September
Temperature
The commencement of September indicates a gentle shift in the average high-temperature, receding from August's hot 93°F (33.9°C) to a still tropical 87.6°F (30.9°C). Shumaker registers a prominent dip from daytime highs, with an average of 66°F (18.9°C) during the nights of September.Heat index
The heat index in September is calculated to be a very hot 100.4°F (38°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
