Weather in August

The last month of the summer, August, is another hot month in Waynesville, Missouri, with an average temperature varying between 65.8°F (18.8°C) and 87.3°F (30.7°C).

Temperature

The commencement of August notes an average high-temperature of a still hot 87.3°F (30.7°C), exhibiting little difference from the previous month. Waynesville observes an average nighttime temperature of 65.8°F (18.8°C) during August.

Heat index

Throughout August, the heat index is computed to be a sweltering 100.4°F (38°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
