Best Time to Visit Boston
Boston has strong seasonal character. September and October are excellent travel months. Fall foliage peaks in mid-to-late October, turning the Public Garden, the Esplanade, and neighborhoods like Beacon Hill into postcard scenes. Temperatures drop to 10C to 18C but stay comfortable for walking Freedom Trail and the harborfront. June and July bring warm weather (22C to 28C), active outdoor markets, and the Boston Harborfest in July. August humidity can make the city feel sticky but the beaches in nearby Gloucester and Cape Cod are in peak season. The Boston Marathon in April is the city's biggest annual event, drawing 500,000 spectators; the route from Hopkinton to Copley Square passes through Brookline and Back Bay. Winter (December to March) is cold with potential snow. December has holiday charm in the Back Bay and Christmas displays on Commonwealth Avenue. January and February are the quietest and coldest months.
