Weather in August
Temperature
Marysville greets August with an average high-temperature of a still moderately hot 81.5°F (27.5°C), marking a slight deviation from the preceding month. August's nights observe an average temperature of 62.6°F (17°C).Heat index
The heat index in August is evaluated at a tropical 87.8°F (31°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
