Weather in August
Temperature
August's onset records an average high-temperature of a still hot 92.3°F (33.5°C), a near match to July's 93.4°F (34.1°C). Durham experiences a steady low-temperature of 71.2°F (21.8°C) throughout August.Heat index
The heat index in August is computed to be a fiery hot 98.6°F (37°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. 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. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
