Weather in August

The last month of the summer, August, is another warm month in Catharpin, Virginia, with an average temperature varying between 85.6°F (29.8°C) and 65.8°F (18.8°C).

Temperature

The onset of August marks an average high-temperature of a warm 85.6°F (29.8°C), hardly differing from July's 88.2°F (31.2°C). In the month of August, the temperature generally rests at an average low of 65.8°F (18.8°C).

Heat index

August's heat index is estimated at a torrid 95°F (35°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Observations indicate that the heat index values are for shady locations with light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. 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. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
