Weather in August
Temperature
The average high-temperature in August, at a still tropical 87.6°F (30.9°C), reveals a modest deviation from July's 88.5°F (31.4°C). During August, the temperature in Jacksonville is averaged to a low of 73°F (22.8°C) at night.Heat index
August's average heat index is computed to be a scorching 104°F (40°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the 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 primarily vital for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
