Weather in June
Temperature
With the beginning of June, Potomac's average high-temperature sees a minor increase, transitioning from 74.3°F (23.5°C) in May to a still moderately hot 82.2°F (27.9°C). Potomac's nights in June experience an average temperature drop to a comfortable 63.5°F (17.5°C).Heat index
The heat index value during June is calculated to be a hot 87.8°F (31°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular importance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
