Weather in July
Temperature
With average high and low temperatures of 84.9°F (29.4°C) and 67.1°F (19.5°C) respectively, July is Fairfax's warmest month.Heat index
The heat index value for July is computed to be a fiery hot 96.8°F (36°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
