Weather in June
Temperature
The arrival of June sees a shift in the average high-temperature, moving from a moderately hot 73.8°F (23.2°C) in May to a still warm 84.4°F (29.1°C). In Rockville, the average nighttime temperature during June is a refreshing 66.7°F (19.3°C).Heat index
In June, the heat index is estimated at a fiery hot 95°F (35°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
