Weather in June
Temperature
With the onset of June, Duke's average high-temperature experiences a rise, moving from May's warm 82.2°F (27.9°C) to a tropical 93.4°F (34.1°C). Duke's June nights cool down to an average low-temperature of 72.1°F (22.3°C).Heat index
The heat index value for June is evaluated at a blisteringly hot 104°F (40°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
