Weather in May

May, the last month of the spring in Somerville, is a warm month, with an average temperature fluctuating between 64.8°F (18.2°C) and 81.1°F (27.3°C).

Temperature

The start of May signals a slight increase in the average high-temperature, moving from an agreeable 72.7°F (22.6°C) in April to a moderately hot 81.1°F (27.3°C). During the nights in May, the temperature averages to a refreshing 64.8°F (18.2°C).

Heat index

The heat index value during May is evaluated at a hot 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.
Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
