Weather in September
Temperature
Spring Hill's shift from August to September is accompanied by an average high-temperature of a still tropical 88.2°F (31.2°C), a slight deviation from 89.8°F (32.1°C). Spring Hill, during September nights, observes an average temperature of 73.6°F (23.1°C).Heat index
During September, the heat index is computed to be a blisteringly 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.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

A UV Index reading of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the average person.Note: The daily high UV index of 7 in September translates into this advice:
Fend off overexposure. Sun protection is vital. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
