Weather in August
Temperature
As Gillette welcomes August, the average high-temperature stabilizes at a still moderately hot 82.4°F (28°C), showing little deviation from July's 84.7°F (29.3°C). Throughout August, the nighttime temperature averages to a refreshing 62.4°F (16.9°C).Heat index
For August, the heat index is computed to be 82.4°F (28°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
