Weather in August
Temperature
As Winner, South Dakota, steps into August, the average high-temperature is measured at a warm 85.8°F (29.9°C), displaying minor differences from July's 88°F (31.1°C). Winner logs a notable disparity from the daily highs during August, as the nighttime temperature lowers to an average of 63.9°F (17.7°C).Heat index
August's average heat index is computed to be a hot 89.6°F (32°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and 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 hold great significance to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
