Boston Snow Day Predictor: Will Boston Schools Close Tomorrow?
Most of Boston's big snowstorms are nor'easters that track up the coast, and a few miles can decide whether the city gets heavy snow or rain.
Boston Public Schools serves the whole city; surrounding districts such as Cambridge and Newton make their own decisions, so one town can close while the next one opens.

How much snow closes school in Boston?
Boston gets about 52" of snow in a normal year (NOAA 1991–2020 normals, averaged from 6 nearby stations including Boston Logan Intl. Airport, Hingham, Blue Hill Coop). Based on that, our model treats about 6" of overnight snow as the point where a closure becomes a coin flip. Less than half of that rarely closes schools here; one and a half times that usually does.
