Weather in June
Temperature
The onset of June brings a temperature shift, with the average high-temperature moving from a moderately hot 75.7°F (24.3°C) in May to a still warm 85.8°F (29.9°C). In June, Mount Vernon's temperature tends to fall to an average low of 66.2°F (19°C) during the night.Heat index
During June, the heat index is estimated at a fiery hot 96.8°F (36°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 hold particular importance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
