Weather in August
Temperature
August welcomes an average high-temperature of a still warm 82°F (27.8°C), not much different from the preceding month. During the month of August, Yorktown experiences a steady low-temperature average of 62.6°F (17°C).Heat index
August's heat index is estimated at a hot 87.8°F (31°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
