Massachusetts Weather & Climate Guide 2026

Massachusetts's climate in numbers — the months that flatter it, the ones to avoid, and what to pack.

Massachusetts is a historic New England state in the northeastern United States, home to world-renowned universities, revolutionary history, and stunning natural landscapes. From the cosmopolitan city of Boston to the scenic shores of Cape Cod and the Berkshire Mountains, Massachusetts offers a remarkable blend of culture, history, and outdoor adventure.

Massachusetts has a classic four-season New England climate. Summers are warm with occasional humidity (78-88°F highs); falls are spectacular with brilliant foliage; winters are cold and snowy (averages 43 inches annually in Boston); springs arrive slowly with flowering trees in May. The coast moderates temperatures — Cape Cod is slightly milder than inland. The Berkshires are generally cooler and snowier.
