Weather in August
Temperature
August commences with an average high-temperature of a warm 84.9°F (29.4°C), showing little deviation from July's 86.2°F (30.1°C). In August, the average low-temperature is a comfortable 66.2°F (19°C).Heat index
The heat index in August is calculated to be a torrid 95°F (35°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Note that heat index values are valued for light wind and location in the shade. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
