Weather in August
Temperature
August's arrival brings an average high-temperature of a still tropical 87.4°F (30.8°C), slightly deviating from July's 90°F (32.2°C). Throughout August, Callahans Corner witnesses a consistent average low-temperature of 67.6°F (19.8°C).Heat index
August's heat index is estimated at a torrid 100.4°F (38°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital 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.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
