Boston vs Portland

Boston

Boston has a humid continental climate with four sharply defined seasons. Winters are cold and snowy, summers are warm and humid, and spring and fall can be glorious. Proximity to the Atlantic moderates extremes but also brings nor'easter storms in winter and occasional sea fog in summer.

Portland

Portland has a cool marine climate — famously rainy, but not in the way visitors expect. The rain is a persistent drizzle, not heavy downpours. Portland actually receives less annual rainfall (about 36 inches) than New York or Houston, but it is spread over 150+ rainy days from October through May. Summers (July through September) are gloriously dry, sunny, and warm. Winter brings occasional snow that typically melts within a day or two.

Boston

Boston's MBTA — simply "the T" — covers the city with subway, trolley, commuter rail, bus, and ferry. The subway is the oldest in the Americas, compact, and perfect for most visitor itineraries. A CharlieCard (reloadable) or CharlieTicket (paper) is used across the system. Driving is painful — narrow one-way colonial street grids, no numbered system, and notoriously aggressive drivers.

Walkability: Central Boston is one of the most walkable areas in the US. Beacon Hill, the North End, Back Bay, Downtown, and the Waterfront are tightly packed and best explored on foot. The Freedom Trail is literally a walking itinerary. Cambridge is also very walkable once you cross the river. Winter ice is the main challenge; summer heat rarely stops walking.

Portland

Portland has the most useful public transit of any city its size on the West Coast. MAX light rail (5 lines) connects the airport, downtown, and key suburbs. The Portland Streetcar loops through downtown, the Pearl, and east side neighborhoods. TriMet buses fill in the gaps. Within individual neighborhoods — Pearl, Hawthorne, Alberta, Mississippi, NW 23rd — walking is the right answer. Portland is also one of the best US cycling cities with protected lanes and a cyclists-first culture.

Walkability: Portland is one of the most walkable large cities in the American West — grid-patterned, flat on the east side, and most interesting neighborhoods (Pearl, NW 23rd, Hawthorne, Division, Alberta, Mississippi, Belmont) have dense commercial strips. Downtown blocks are short (only 200 ft) which makes walking feel quicker. Expect rain 9 months of the year — a good waterproof shell is more useful than an umbrella in the Portland wind.
