Rehoboth Beach, DE tide times

Rehoboth Beach is Delaware's largest ocean resort, fronting the Atlantic on a barrier strand with Rehoboth Bay behind it and the Lewes-Rehoboth Canal running along its western edge. Mean tidal range on the ocean face is approximately 1.2 m MLLW — standard for the Delaware barrier coast — with semidiurnal rhythm giving two high and two low waters each day. The inlet at the south end of town at Indian River Inlet (about 10 km south) is the main tidal exchange between the bay and ocean; the ocean beach itself faces open Atlantic swell.

The beach at the foot of the boardwalk is wide at low tide — a low-water strip of compacted sand 60–80 m across where the wave break is furthest from the dune line and beach games, sand castle construction, and tide pool exploration are easiest. High tide pulls the surf to within 20–30 m of the dune line. For swimming families, mid-tide offers the most comfortable entry: water is shallow over a gradually sloping bottom, and the wave face hasn't yet steepened as it does at low tide when it breaks on the outer bar. Lifeguard zones are active from Memorial Day through Labor Day.

Surf conditions at Rehoboth are modest by mid-Atlantic standards — head-high waves occur on northeast and northeast-east swells in autumn and winter, but summer sessions are often waist-high or smaller. The tide phase still matters: low tide can expose the outer sandbar and create a punchy shore break, while a mid- to high-tide session typically produces longer, slower walls. The inlet jetties at Indian River, reachable by a short drive, produce more consistent breaks when swell is running.

Rehoboth Bay behind the barrier is effectively non-tidal for most recreational purposes — the inlet restriction limits tidal exchange and the bay's large surface area means range is a few centimetres under typical conditions. This makes it ideal for stand-up paddleboarding, kayaking, and flat-water rowing at any tide stage. The Lewes-Rehoboth Canal along the town's northern edge carries more tidal current — up to 0.5 knots on a strong tide — and is a workable SUP or kayak route on calm days.

For anglers, the ocean surf line is productive for striped bass and bluefish from September through November on either side of the low-tide trough. Pompano and kingfish work the inshore bar through summer. The bay supports flounder, weakfish, and speckled trout in the grass channels; boat ramps on Rehoboth Bay give access to deeper holding water on the ebb.

Tide predictions shown here come from Open-Meteo Marine global model output, which provides useful planning horizons but carries uncertainty of ±45 minutes on timing and ±0.2–0.3 m on height. The nearest NOAA CO-OPS station with published predictions for this area is Lewes (station 8557380, approximately 10 km north); verified predictions there are the most accurate proxy for Rehoboth ocean beach tides, with times running roughly 5 minutes earlier than Lewes.
