Weather in August
Temperature
August commences with an average high-temperature of a warm 85.5°F (29.7°C), showing little deviation from July's 86.5°F (30.3°C). During August, Swann perceives a consistent contrast from the daytime highs, with an average low-temperature of 62.2°F (16.8°C).Heat index
The average heat index in August is computed to be a fiery hot 95°F (35°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
