Temperature

June's arrival shows an average high-temperature of a still tropical 31.8°C (89.2°F), hardly different from the previous month. The mean low-temperature during June nights in Boston is a pleasant 21.8°C (71.2°F).

Heat index

The heat index value during June is appraised at a life-threatening hot 45°C (113°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Resist overexposure. Safeguarding from solar damage is indispensable. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. Take warning! Reflective sand and water surfaces intensify the Sun's UV rays.
