Weather in July
Temperature
Jacksonville's temperatures peak on average in July, reaching 89.2°F (31.8°C) at their highest and 69.3°F (20.7°C) at their lowest.Heat index
Throughout July, the heat index is evaluated at an extremely hot 107.6°F (42°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for average individuals.Note: A maximum UV index of 6 in July translates into the following recommendations:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
