Weather in August
Temperature
As July turns into August, the average high-temperatures rest at a still hot 87.4°F (30.8°C), showing a minor variation from the prior month. Bellevue experiences an average nighttime temperature of 68.4°F (20.2°C) in the month of August.Heat index
Throughout August, the heat index is estimated at a very hot 100.4°F (38°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
