Weather in August
Temperature
The advent of August sees the average high-temperature at a still moderately hot 80.6°F (27°C), subtly shifted from July's 82°F (27.8°C). Donnelly experiences a drastic reduction from day temperatures to an average low of 58.6°F (14.8°C) in August.Heat index
August's mean heat index is computed to be 84.2°F (29°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
