Weather in August

August in Waukee marks the gradual transition from the hot summer to the chillier autumn season. Compared to July, the temperatures mildly decrease, signaling the draw of autumn around the corner. The advent of moderate weather conditions invites residents to enjoy outdoor activities before fall officially takes the stage. Similarly, the relative humidity drops ever so slightly with temperatures not straying far from an 81.3°F (27.4°C) high. Waukee's August weather encapsulates the perfect summer send-off, leading seamlessly into the fall season.

Temperature

Waukee's weather, upon August's arrival, documents an average high-temperature of a still warm 81.3°F (27.4°C), nearly identical to the prior month. Waukee records a steady low-temperature average of 62.4°F (16.9°C) during August.

Heat index

August's mean heat index is calculated to be a hot 87.8°F (31°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.
The metrics for the heat index are tailored for both shady environments and light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
