Bethany Beach, DE 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.

Conditions as of 00:00 local time. Refreshes daily.

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 Tue 12 May (range 1.2m / 4.0ft). 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.

Bethany Beach sits near the southern end of Delaware's ocean coast, separated from Maryland's Fenwick Island by a few kilometres of undeveloped barrier strand. It earns its reputation as the 'quiet resort' of the Delaware shore — lower density, narrower commercial strip, and a beach culture more oriented toward families and shorebird watchers than nightlife. Tidal range on the ocean face is approximately 1.1 m MLLW, among the smaller values on the Delaware coast, with semidiurnal rhythm producing two daily tide cycles. The barrier beach at Bethany is wide and low-profile, with a gradual nearshore slope that produces gentle wave break across most of the tidal range — a significant factor for families with children. At mean lower low water, the exposed beach extends 50–70 m seaward of the high-tide wrack line, and the exposed sand at the water's edge is firm enough for walking, jogging, and shore fishing without equipment. The beach narrows by approximately half at high water but retains enough dry sand above the wrack line for a full beach setup. Little Assawoman Bay lies immediately behind the barrier, connected to the ocean by the Assawoman Canal and the inlet at Fenwick Island. Like Rehoboth Bay, the bay is heavily restricted from tidal exchange, making it effectively non-tidal for recreational planning. The calm surface and shallow depth make it ideal for kayaking and SUP, particularly in morning before sea breezes build. The bay's grass beds support a diverse shorebird assemblage — great blue heron, snowy egret, willet, and dunlin forage the exposed mudflats at low water on the bay side of the barrier, reaching maximum density roughly 2 hours before and after low tide. For birders, Bethany's real draw is the concentration of shorebird habitat at the Assawoman Wildlife Area, which spans the marsh just north of town. The wildlife area is accessible by kayak from the canal; the optimal visit is timed to arrive at the bay mudflats 1–2 hours before low water, when birds are still arriving from roosting sites and feeding activity is high. Surf fishing from the Bethany beach is productive for summer flounder (fluke) in the inner trough from June through August, and for stripers and bluefish in autumn. The gentle slope produces a well-defined inner trough that concentrates fish at low tide. The fewer crowds compared to Rehoboth mean accessible beach driving permits (Delaware beach driving permit required) can be used more comfortably at Bethany's northern and southern ends during off-peak mornings. Tide times for Bethany Beach are sourced from Open-Meteo Marine model output, with planning uncertainty of ±45 minutes on timing and ±0.2–0.3 m on height. The nearest NOAA CO-OPS reference station is Indian River Inlet (station 8558690), located approximately 8 km north. Official harmonic predictions there provide the most accurate local tide window; Bethany times run within a few minutes of Indian River Inlet.
