Weather in August
Temperature
Transitioning into August, Roosevelt experiences an average high-temperature of a still moderately hot 84.7°F (29.3°C), marking a minor shift from the preceding month. August, marked by an average low-temperature of 61.3°F (16.3°C), indicates a large temperature drop from the daytime peak.Heat index
The heat index value during August is estimated at 84.2°F (29°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
