The Boston Public Schools and surrounding Massachusetts districts together serve thousands of students across many public, charter, and private campuses. The Boston area averages approximately 56 inches of snowfall per year, with the heaviest snowfall typically occurring between December and March.
School districts in Boston generally announce closures through their official websites, automated phone calls, local TV, and radio stations, with most decisions made by the superintendent in the early morning hours, typically by 5:00 AM on storm days. Two-hour delays and remote-learning days are sometimes used in Boston as alternatives to a full closure when conditions are borderline.
Boston's geography plays a meaningful role in its winter weather: a humid continental coastal climate where nor'easters can rapidly intensify and dump several feet of snow. These factors directly influence how often Boston schools end up closed during a given winter. Geographically, Boston sits near 42.36°N, 71.06°W, which shapes how regional storm systems and Arctic air masses interact with the area.
Notable historic snow events in or near Boston include the historic 2015 Boston-area season that broke all-time snowfall records, which produced widespread closures across the region. Historically, schools in the Boston area close an average of approximately 6 days per winter season due to snow, ice, or extreme cold.
