Boston, Massachusetts Weather in April

April's changeable weather

April feels like a proper transition into spring, not reliable warm weather. Daytime highs reach 13°C, but nights can dip to 3°C. Rain falls on 11 days, and the sky is often cloudy. You might get a bright afternoon for walking the Freedom Trail, then need a dry indoor stop when showers arrive.

The Public Garden and Boston Common start to feel inviting, though wet paths can make a long stroll less pleasant. Save beach plans for another month; the water and air are still chilly. For families, the New England Aquarium is a handy rainy-day choice.

Marathon Monday

Patriots' Day brings the Boston Marathon, usually held in April. Crowds gather along the route and near the finish on Boylston Street. It's a lively day, but street closures can slow trips around Back Bay and Copley Square.

Want a quieter city break? Visit outside Marathon weekend, when the race-day crowds are gone and spring walks feel more relaxed. The marathon can also push up hotel prices near the route, so don't assume April is uniformly cheap.

A shoulder-season visit

Compared with summer and the busy fall season, April is generally a quieter, less expensive time to visit Boston. It's not as mild as May, and wet weather can interrupt plans, but museums and historic sights work well whatever the sky does.

A useful local tip: if you're heading to the Museum of Fine Arts, take the Green Line's E branch to Museum of Fine Arts station. It saves you a longer walk from Back Bay on a rainy day. Check the route on the day, since service changes can affect your trip.
