WeatherBoston's best season is May-October, with late spring and early autumn being most pleasant. The sea breeze keeps the city cooler in summer (average mean temperature 71 F/22 C) and more moderate in winter than its latitude might indicate, but unseasonably hot or cold weather may occur at any time. In a word, Boston's weather is changeable, so expect alternating sun and precipitation all year. The ocean's proximity also means that Boston has fairly high humidity levels, which can make heat sticky and cold biting (humidity averages 56%-76%). Winters are damp and cold (average temperature is 31 F/-1 C), with abundant rain, sleet and snow that often turns to gray slush or ice.
