Weather in Boston

Best time to visit

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. In autumn, between September and November, the white church steeples of the suburbs create a stunning contrast to the turning colours of the surrounding trees. The other best times to visit are spring and summer. During the summer, average highs are around 27°C (81°F). Fog can also be a problem in spring and summer, and the occasional tropical storm can threaten the region in the autumn. It's best to bring plenty of layers.
