Weather in August
Temperature
August is the warmest month of the year, registering average temperatures as high as 81.7°F (27.6°C) and as low as 55.6°F (13.1°C).Heat index
The heat index in August is calculated to be 84.2°F (29°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Heat index determinations are made taking into account the shade and light air movements. 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 'felt air temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
