Massachusetts Weather


The weather conditions in Massachusetts change quickly, especially along the coastal areas.

Those coastal areas enjoy moderate temperatures, both in summer and winter, when compared to central and western Massachusetts.

Cape Cod, Martha's Vineyard and Nantucket are kept cooler in the summer months by ocean breezes.

Statewide, spring months are pleasant, summers are comfortably mild, late fall is cool and crisp, and winters are cold (on average), with considerable snowfall.

The statewide average high temperature in July approaches 80 degrees, while in January, high temps are usually in the low 30s.

Across the state average precipitation levels are near 45 inches, with slightly higher amounts in the Berkshire Hills, and in the coastal areas, south of Boston.
