Weather in September

The first month of the autumn, September, is also a hot month in Whitfield, Florida, with an average temperature fluctuating between 86.9°F (30.5°C) and 77.4°F (25.2°C).

Temperature

In September, the average high-temperature registers at a still hot 86.9°F (30.5°C), nearly identical to August's 88.5°F (31.4°C). Throughout the nights in September, an average low-temperature of 77.4°F (25.2°C) is noted.

Heat index

September's heat index is evaluated at a sweltering 100.4°F (38°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Note that heat index values are valued for light wind and location in the shade. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Caution! Sand and water reflections can notably increase the UV radiation intensity.
