Weather in July

July is a tropical summer month in Hamilton, Virginia, with an average temperature fluctuating between 65.5°F (18.6°C) and 86.5°F (30.3°C).

Temperature

July registers as the month with the highest average temperatures, reaching 86.5°F (30.3°C) at its peak and 65.5°F (18.6°C) at the lowest.

Heat index

July's average heat index is estimated at a sweltering 98.6°F (37°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
