Weather in August
Temperature
The arrival of August in Gainesville is marked by an average high-temperature of a moderately hot 85.8°F (29.9°C), bearing a close resemblance to July. During August, the temperature is averaged to a low of 65.8°F (18.8°C) at night.Heat index
August's mean heat index is calculated to be a sweltering 96.8°F (36°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
