Unpredictable and exciting — temperatures can swing from the 30s to 70s°F within the same week. Snow is still possible through mid-April in northern New England. Nor'easters can bring heavy, wet snow in March and April. By May, temperatures settle into the 60s–70s°F with blooming cherry blossoms, lilacs, and flowering trees. Mud season in Vermont and Maine makes dirt roads challenging from mid-March through April. Spring thunderstorms become more common in May.

The crown jewel of Northeast weather. September brings warm days in the 70s and cool nights in the 50s.
