Weather in June
Temperature
The start of June brings a subtle rise in the average high-temperature, moving from a moderately hot 74.1°F (23.4°C) in May to a still warm 81.1°F (27.3°C). During June, Williamstown records an average temperature of 59.7°F (15.4°C) at night.Heat index
The heat index in June is computed to be a tropical 86°F (30°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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.
