Weather in July
Temperature
With average high and low temperatures of 90.3°F (32.4°C) and 67.5°F (19.7°C) respectively, July is Dillwyn's warmest month.Heat index
The heat index in July is estimated at an extremely hot 105.8°F (41°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
