Weather in June
Temperature
With the onset of June, Duke's average high-temperature sees a rise, moving from May's warm 82.2°F (27.9°C) to a hot 93.4°F (34.1°C). June's average low-temperature reading settles at an agreeable 72.1°F (22.3°C).Heat index
June's mean heat index is calculated to be a scorching 104°F (40°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 importance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
