Ocean City, MD tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are America/New York local. Folk tradition, not a scientific forecast.

Next spring tide on Mon 11 May (range 1.1m / 3.5ft). Last neap on Wed 06 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Ocean City sits on a narrow barrier island between the Atlantic Ocean and Isle of Wight Bay, with Assateague Island beginning immediately at its southern end. The ocean face runs semidiurnal tides with approximately 1.0 m mean range MLLW — the smallest mean range of any of Maryland's tidal stations, consistent with the slightly more southerly exposure on this section of the Delmarva coast. Isle of Wight Bay behind the boardwalk is near-flat; tidal range there is a few centimetres, entirely controlled by the hydraulic restriction of Ocean City Inlet. Ocean City Inlet is the structural centre of the local tidal story. The inlet, stabilised by the Army Corps of Engineers with twin stone jetties in the 1930s, is the only tidal channel connecting the coastal bays from Ocean City south to Virginia with the Atlantic. Its navigated channel handles a mix of recreational fishing vessels, charter boats, commercial traffic, and the Assateague Island ferry. Tidal current through the inlet reaches 1.5–2 knots on spring ebb, enough to significantly affect vessel handling. The inlet has been dredged to a maintained depth of approximately 3 m MLLW; shoaling can reduce this between maintenance cycles and after major storms. Assateague Island begins at the southern jetty of the inlet, and the contrast between the two barriers is sharp. Ocean City is fully developed; Assateague is federally managed, undeveloped, and home to the famous feral horse herd. The beach on the Assateague side of the inlet is accessible by boat or on foot across the inlet (ferry in season). Low tide exposes wide sandy flats on the Assateague ocean beach that are frequently used for surf fishing — access is easiest and the flat widest at mean lower low water, approximately 1.0 m below the high-tide line. Surf fishing from the Ocean City beach is one of the most popular activities on the Maryland coast. Red drum, striped bass, and bluefish all run the Ocean City surf on moving tides, with early morning outgoing tide from October through November consistently productive for trophy stripers. The 10th Street pier and the jetty faces at the inlet provide structure fishing; the jetty south face on the flood tide concentrates bait-chasing blues in summer. Flounder anglers work the inlet channel edges where current and sand meet. For families, the 3-mile boardwalk runs the full ocean face of the island, and the beach at its foot is widest and shallowest mid-tide. High tide reduces the dry beach strip; at very high water during storms, overwash can reach the boardwalk at lower elevation sections north of the commercial core. The Isle of Wight Bay side is protected from ocean swell and usable for stand-up paddleboarding, kayaking, and sailing at any tide stage given its near-zero tidal variability. Tide predictions on TideTurtle use Open-Meteo Marine model output, which provides useful planning horizons but carries uncertainty of ±45 minutes on timing and ±0.2–0.3 m on height. NOAA CO-OPS station 8570283 (Ocean City Inlet) provides the authoritative local tide gauge record — use it for inlet navigation planning and any activity where precise low-water timing matters.
