Weather in August
Temperature
The arrival of August brings an average high-temperature of a still tropical 86.9°F (30.5°C), subtly diverging from July's 88.3°F (31.3°C). During August, Walnut Creek witnesses a consistent average low-temperature of 70.3°F (21.3°C).Heat index
August's average heat index is calculated to be a torrid 102.2°F (39°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.The heat index's values are generally associated with conditions in shade and light breezes. 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 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
