Climate and Weather in New England

Climate Overview

New England has a harsh, fairly rainy continental climate. Winters are long, cold, and snowy, with daily averages often below or near freezing between December and February. Blizzards, which frequently blow through, intensify the cold. In contrast, summers are pleasant but also wet, with rain and thunderstorms contributing to the region’s lush greenery. In between, both spring and autumn (including its famous Indian summer) are mild but still quite rainy.

However, there are some differences between the north and south of New England. The Boston area and below (Connecticut and Rhode Island) enjoy a slightly milder climate, with shorter, less snowy winters, higher temperatures, and more sunshine. Summers are also warmer there.

Best Time to Visit New England
