- Astronomical Low Tide in Maryland, January 2 to 3, 2008A persistent gale force northnorthwest flow down Chesapeake Bay caused blow-out tides to occur from the late evening of the 2nd into the morning of the 3rd along the Eastern Shore. Many sailboats and some deep-draft powerboats were agrounded in the harbors.
- Astronomical Low Tide in Maryland, February 26, 2012The residual effect from the strong west winds circulating around an intense low pressure system moving through the Canadian Maritimes (it bottomed at 963 millibars at 1 p.m.
- Astronomical Low Tide in Maryland, February 15 to 16, 2015The very persistent and strong to damaging northwest winds that started overnight on the 14th caused blowout tide conditions during both low tide cycles on the Upper Chesapeake Bay and the evening low tide cycle on central Chesapeake Bay on the 15th.
- Coastal Flood and Astronomical Low Tide in Maryland, October 29 to 31, 2025Low pressure off the Mid-Atlantic coast combined with high pressure in Canada, resulting in a lengthy period of northeasterly onshore flow. Increasing tidal anomalies resulted in moderate to locally major tidal flooding over an extended period.
- Coastal Flood and Astronomical Low Tide in Maryland, October 18 to 19, 2025South and southwesterly winds developed ahead of a strong cold front. Winds became westerly behind the front, allowing water trapped in the middle Chesapeake Bay to flood portions of the Maryland Eastern Shore.
