Temperature

The transition into June notes an average high-temperature of a still tropical 89.6°F (32°C), revealing a mild distinction from the 86°F (30°C) in May. In the month of June, Harvard's average low-temperature falls to a pleasant 72.5°F (22.5°C).

Heat index

The average heat index in June is evaluated at an extremely hot 109.4°F (43°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

In June, the average relative humidity is 76%.

Rainfall

UV index

Note: During June, 7 as the daily maximum UV index converts into the following advice:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
