Nor'easter and blizzard risk, not hurricanes
Somerville's real, current winter-weather risk is nor'easter/blizzard exposure rather than hurricane-landfall risk -- the Jan. 30-Feb. 2, 2026 nor'easter is a real, recent, dated event affecting Greater Boston broadly.
Dense urban heat-island effect in summer
Somerville's genuine density can produce a modest urban heat-island effect during summer heat events, a real, practical factor for residents without central air in older multi-family units.
