Temperature

In Sumterville, Florida, the months of July and August are known for the peak temperatures, reaching an average high of 90.1°F (32.3°C).

Heat index

For most parts of July, the heat index is computed to be a life-threatening hot 113°F (45°C). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. 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 particularly relevant to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Note: A daily high UV index of 7 in July leads to these guidelines:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
