Weather in August
Temperature
Welcoming August, Smithfield notes an average high-temperature of a still tropical 86.2°F (30.1°C), nearly consistent with July's 88°F (31.1°C). In August, the nighttime temperature in Smithfield, Virginia, lowers to an average of 71.2°F (21.8°C).Heat index
For most parts of August, the heat index is calculated to be a torrid 96.8°F (36°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
