Weather in August
Temperature
August's onset records a minor alteration in the average high-temperature to a moderately hot 84.9°F (29.4°C) from July's 86°F (30°C). Fincastle reports a steady low-temperature average of 61.9°F (16.6°C) throughout August, revealing a large deviation from the daytime high.Heat index
In August, the average heat index is calculated to be a fiery hot 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. 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 'felt air temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
