Weather in June
Temperature
June's onset witnesses a minor shift in the average high-temperature, moving from 74.8°F (23.8°C) in May to a still moderately hot 82.9°F (28.3°C). In Jermantown, the average nighttime temperature during June is an enjoyable 63.5°F (17.5°C).Heat index
The heat index value for June is calculated to be a tropical 89.6°F (32°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
