Weather in August
Temperature
At the onset of August, Jacksonville records an average high-temperature of a still hot 90.1°F (32.3°C), showing little deviation from the preceding month. In Jacksonville, the expected average low-temperature for August is a pleasant 70.9°F (21.6°C).Heat index
August's average heat index is estimated at an extremely hot 107.6°F (42°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Remember, devices such as parasols or canopies might not provide complete sun protection. Opt for tightly woven and loose clothing to enhance protection from the Sun.
