Weather in Boston

Best time to visit

Modern Boston is very much a microcosm of New England. It has the typical east coast climate of hot, humid summers and freezing, snowy winters. In autumn, between September and November, the white church steeples of the suburbs create a stunning contrast to the turning colours of the surrounding trees. The other best times to visit are spring and summer. During the summer, average highs are around 27°C (81°F). Fog can also be a problem in spring and summer, and the occasional tropical storm can threaten the region in the autumn. It's best to bring plenty of layers.

Last updated: We update the weather data for Boston from our weather partner every four hours. The time the last update was received is detailed here.
Actual Forecast Location: We have 830+ weather locations on the worldtravelguide.net website. Where no exact location is available we have used the nearest appropriate forecast point.
Symbols indicate the predominant weather for the day in question, calculated based on a weighting of different types of weather. So if a day is forecast to be sunny with the possibility of a brief shower, then we will see a sunny or partly cloudy symbol rather than a rain cloud. For the purpose of this forecast, 'day' is the entire 24 our period 00:00 to 23:59
The maximum temperature is the highest temperature forecast between dawn and dusk, and the minimum temperature is the lowest temperature expected from dusk on the day in question to dawn the next day. The temperature is in °C, or Celsius.
Wind speed and direction are the conditions expected at midday. Wind direction is based on a 16 point compass. W, SW, SSW, etc. The wind direction states where the wind originates. Wind speed is listed in MPH or miles per hour.
Humidity levels indicates how much water vapour the air contains compared to the maximum it could contain at that temperature. As a general guide:
  • 0 to 30 is very low
  • 31 to 50 is low
  • 51 to 70 is moderate to low
  • 71 to 80 is moderate
  • 81 to 90 is moderate to high
  • 91 to 100 is high
Pressure is measured in millibars (mb)
Visibility based on whether the human eye can see the following distances:
  • Very poor - less than 1km
  • Poor - between 1km and 4km
  • Moderate - between 4km and 10km
  • Good - between 10km and 20km
