Weather in August
Temperature
Upon the onset of August, Fairfax witnesses an average high-temperature of a still hot 89.8°F (32.1°C), showing a close resemblance to the prior month. The average temperature during August nights dips to a pleasant 72.9°F (22.7°C).Heat index
For August, the heat index is computed to be a blistering 109.4°F (43°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.Consider that heat index readings are for situations in the shade and light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for ordinary individuals.Note: During August, 7 as the daily maximum UV index converts into the following advice:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Always opt for UVA and UVB-resistant sunglasses on radiant days.
