Weather in August
Temperature
Chapel Hill experiences an average high-temperature of a still hot 86.5°F (30.3°C) with the onset of August, subtly varied from July's 87.4°F (30.8°C). Chapel Hill throughout August, records an average low-temperature of 67.5°F (19.7°C).Heat index
August's average heat index is calculated 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's context suggests values are appropriate for shady areas and slight breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
