Boston rarely experiences either extreme heat or cold.
In the winter, the first freezing temperatures usually occur in early November, but the temperatures are modified considerably by the nearness of the relatively warm ocean.
Frigid weather usually fades out by early April, and Boston typically enjoys a spectacular, colorful spring with moderate temperatures.
Freezing temperatures are common from late November to late March. By May, the temperatures rise to a moderate 60-70 degrees.
Boston has no true dry season as it rains intermittently throughout the year.
Much of the rainfall during the summer and early fall comes from showers and thunderstorms.
At other times during the year, low pressure systems pass frequently and produce rain, on average, one out of three days.
Coastal storms-which Bostonians refer to as "Northeasters"-produce much of the rain and snow. The main snow season occurs from December through March.
Hope this helps, have a good time!
