Tide Levels Chart

The following is a sampling of historic and recent flood levels to help put tidal predictions and observations in context. See real-time and archived tide levels at the Bayside Center  (500 block of Bay Avenue in Ocean City). Add 2.06 feet to convert the NAVD88 readings to mean low water (MLW). See forecasts for tide levels in the coming days.
