Weather in July
Temperature
July is the month when Jacksonville experiences its warmest temperatures, averaging a high of 91.2°F (32.9°C) and a low of 72.1°F (22.3°C).Heat index
The heat index value for July is estimated at an extremely hot 111.2°F (44°C). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.Heat index readings emphasize conditions of light breezes and shaded spots. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
