Weather in September
Temperature
The arrival of September brings an average high-temperature of a still tropical 88.9°F (31.6°C), subtly diverging from August's 90.7°F (32.6°C). Throughout September, Immokalee anticipates an average low-temperature of 75°F (23.9°C).Heat index
The average heat index in September is evaluated at a blistering 109.4°F (43°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Know that the heat index computations account for shaded terrains and slight winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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 quite important for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Shield from overexposure. Defense against sun-related harm is required. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
