Weather in June
Temperature
Johnstons Station's transition into June is noticed by a slight rise in the average high-temperature, advancing from a moderately hot 83.8°F (28.8°C) in May to a tropical 90°F (32.2°C). Johnstons Station sees an average low-temperature of 70.2°F (21.2°C) during June.Heat index
The heat index value during June is computed to be a blistering 109.4°F (43°C). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. 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 'felt air temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and 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 extremely significant for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
