Weather in August
Temperature
August's advent presents an average high-temperature of a warm 85.6°F (29.8°C), indicating a slight variation from the conditions of the previous month. Throughout August, Crestwood experiences a low-temperature average of 66.9°F (19.4°C).Heat index
The average heat index in August is calculated to be a torrid 96.8°F (36°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
