Weather in Boston

Modern Boston is very much a microcosm of New England. It has the typical east coast climate of hot, humid summers and freezing, snowy winters.

Spring (March to May) is a great time to visit Boston, as temperatures are generally mild: between 5°C (41°F) and 23°C (73°F). However, frequent fog can cause it to feel quite chilly. Since temperatures can fluctuate throughout the day, wearing layers is key.

Summer (June to August) sees average highs of around 29°C (84°F) but frequent thunderstorms, causing humidity.

Autumn (September to November) sees the white church steeples of the suburbs create a stunning contrast to the turning colours of the surrounding trees. Temperatures range from 17°C (63°F) to 7°C (44°F) throughout the season.

Winter (December to February) typically brings heavy snowfall, turning the city into a magical winter wonderland despite the freezing weather.
