Weather in August
Temperature
The arrival of August coincides with an average high-temperature of a still moderately hot 81.9°F (27.7°C), indicating a minimal shift from July's 83.8°F (28.8°C). Roosevelt witnesses a consistent average low-temperature of 66.9°F (19.4°C) throughout August.Heat index
The heat index value during August is calculated to be a hot 87.8°F (31°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
