Weather in July
Temperature
In July, Jacksonville's weather conditions record an average high-temperature of a still tropical 94.1°F (34.5°C), demonstrating little divergence from the preceding month. July's average low-temperature reading settles at a pleasant 72.9°F (22.7°C).Heat index
In July, the average heat index is appraised at a burning hot 120.2°F (49°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Note that heat index values are valued for light wind and location in the shade. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
