Weather in August
Temperature
August's advent denotes a minor fluctuation in the average high-temperature to a still moderately hot 81.1°F (27.3°C) from July's 83.5°F (28.6°C). During the nights in August, the temperature averages to a refreshing 63.7°F (17.6°C).Heat index
In August, the average heat index is calculated to be a hot 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
