Local takeaway
Boston lies near a high-variability boundary: coastal storms may be active, but warmer background temperatures can reduce snow efficiency near the coast.
What the 2026–27 El Niño changes
The current outlook favors warmth across the northern tier and eventually extends enhanced precipitation odds along much of the East Coast. That combination can mean more rain/mixed events in lower elevations.
Snow context for Boston, MA
Interior New England historically leans toward reduced El Niño snowfall, while some Mid-Atlantic-adjacent areas can be snowier. Coastal Northeast outcomes vary greatly from one El Niño to another.
Travel context
Expect large swings: a mild seasonal average can still contain major nor’easters and cold outbreaks. Event forecasts matter far more for travel decisions.
