Maryland School Closings
⚠️ Always confirm with your school district directly. This page is for reference only.
Check the latest Maryland school closings, delays, and cancellations today. This page monitors real-time announcements from school districts across Maryland — including Baltimore, Rockville, Annapolis, Frederick, and Hagerstown. Most Maryland superintendents aim to announce closures by 5:00–5:30 AM, though major nor'easter decisions are often communicated the evening before.
School closures in Maryland are most commonly triggered by winter snowstorms and nor'easters, ice storms, freezing rain, and — in spring and summer — severe thunderstorms and tornadoes. District officials coordinate closely with the National Weather Service Baltimore/Washington forecast office and county emergency management agencies to make timely closure decisions. The Washington, DC metropolitan area geography means Montgomery County and Prince George's County districts are often influenced by the same storm systems affecting Northern Virginia and the District.
Many Maryland school systems are authorized to use Asynchronous Learning Days (ALDs) in place of traditional snow days, allowing students to complete coursework online and preserving instructional time without extending the school year. The number of ALDs permitted varies by district — check your school's parent portal (PowerSchool, Canvas, or Infinite Campus) for your district's specific ALD policy and to ensure your contact information is current for automated closure alerts.
