Weather in June
Temperature
In James City, the average high-temperature in June slightly rises, from 79.5°F (26.4°C) in May, to a still warm 85.8°F (29.9°C). Nighttime temperatures in James City consistently average an agreeable 69.4°F (20.8°C) during June.Heat index
For June, the heat index is appraised at a sweltering 96.8°F (36°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
