Weather in June
Temperature
Winchester's weather in June presents a minor rise in the average high-temperature, moving from a moderately hot 74.3°F (23.5°C) in May to a still warm 82.9°F (28.3°C). A noteworthy temperature dip to a refreshing 55.4°F (13°C) is observed during the nights of June.Heat index
June's heat index is estimated at 84.2°F (29°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
