Weather in August
Temperature
Winston-Salem records a slight change with August's average high-temperatures adjusting to a still tropical 87.4°F (30.8°C) from July's 89.8°F (32.1°C). During August, the temperature tends to dip to an average of 66.7°F (19.3°C) at night.Heat index
In August, the heat index is appraised at a fiery hot 98.6°F (37°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical 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 hold particular importance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
