Weather in July

July in Round Hill, Virginia, is a hot summer month, with an average temperature ranging between min 65.5°F (18.6°C) and max 86.5°F (30.3°C).

Temperature

July, recognised by an average high temperature of 86.5°F (30.3°C) and a low of 65.5°F (18.6°C), is Round Hill's warmest month.

Heat index

July's average heat index is appraised at a sweltering 98.6°F (37°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
