Massachusetts Frost Dates
Massachusetts offers a moderate growing season with clear differences between the coast, the Connecticut River Valley, and the hill towns. Ocean influence can soften frost near the shore, while higher inland terrain often sees cooler nights and a longer wait for tender planting.
