A first look at Boston

Spend the first day on a manageable historic-street route and the North End, then choose a garden and harbor outing for the second. Leave time for individual admissions and meals instead of racing to every Freedom Trail stop.

Weather guide

Weather in Boston

Winter needs insulating layers and footwear with grip; summer calls for breathable clothes and rain protection. NOAA Logan Airport 1991–2020 monthly normals provide a seasonal baseline, while exposed harbor wind and actual travel dates need a current forecast.

15–19°C

Changeable temperatures with cooler mornings and evenings; keep rain protection accessible.

What this means for packing

October calls for a shirt, removable sweater and rain-resistant jacket. Garden paths and exposed waterfront pauses may need more warmth than a brisk downtown walk. Shoes with grip help on wet leaves; put the longer outdoor route in daylight and check reduced site schedules.

Choosing a season

The best-season badge suggests months for general sightseeing, using the typical daytime temperatures and rainfall in our monthly guides. Beach holidays, festivals, winter sports and northern lights trips may suit different dates.

Climate methodology

NOAA NCEI Boston Logan International Airport station USW00014739, 1991–2020 normals: mean daily maximum 62.1°F (16.7°C), minimum 47.5°F (8.6°C); monthly precipitation 4.03 inches (102.4 mm). Clothing bands convert to Celsius, round and expand 2°C each way; these are outfit prompts, not forecast limits. Precipitation includes water-equivalent snow. Airport exposure differs from sheltered city streets and harbor decks; check your actual travel dates.
