Weather in August
Temperature
Stepping into August, Winterset records an average high-temperature of a still warm 81.5°F (27.5°C), almost consistent with July. Throughout August, the temperature falls to an average low of 62.6°F (17°C).Heat index
The average heat index in August is computed to be a hot 87.8°F (31°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
