Weather in June
Temperature
Washington's transition into June sees a rise in the average high-temperature, advancing from a warm 77.7°F (25.4°C) in May to a hot 88.2°F (31.2°C). In June, the temperature in Washington drops to an average of 69.8°F (21°C) at night.Heat index
During June, the heat index is estimated at a torrid 100.4°F (38°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Heat index determinations are made taking into account the shade and light air movements. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
