Weather in August
Temperature
August reports an average high-temperature of a still warm 81.3°F (27.4°C), slightly varied from July's 82.2°F (27.9°C). Mercer anticipates a considerable cooling off from the daytime high to an average minimum temperature of 59°F (15°C) in August.Heat index
Throughout August, the heat index is computed to be 82.4°F (28°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.The standards for the heat index are set for locations in shade and under light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
