Weather in June
Temperature
Dorchester perceives a slight temperature ascent during June, with average high-temperatures adjusting from a warm 73.9°F (23.3°C) in May to a still moderately hot 82.2°F (27.9°C). In Dorchester, June nights cool down to an average of 65.5°F (18.6°C).Heat index
Throughout June, the heat index is estimated at a tropical 89.6°F (32°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
