Weather in August
Temperature
The arrival of August denotes a barely perceptible change in the average high-temperatures to a moderately hot 85.6°F (29.8°C) from July's 87.6°F (30.9°C). In Lake Barcroft, an average low-temperature of 67.3°F (19.6°C) is recorded during August nights.Heat index
The heat index in August is computed to be a fiery hot 95°F (35°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for ordinary individuals.Note: A maximum UV index of 6 in August translates into the following recommendations:
Guard oneself from overexposure. Defence against sun injury is vital. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. To best shield against UV radiation, choose sun-safe garments and dependable sunglasses.
