Weather in June
Temperature
As June begins, there's a slight increase in the average high-temperature, moving from a moderately hot 74.8°F (23.8°C) in May to a still warm 82.8°F (28.2°C). McLean experiences an average low-temperature of 63.9°F (17.7°C) in month of June.Heat index
June's heat index is appraised at a hot 87.8°F (31°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
