Which tide station covers Rehoboth Beach?
Rehoboth Beach has no NOAA tide station of its own, so the predictions on this page come from the nearest one: Lewes (Lewes, DE), about 5 miles away. Along an open coast the high and low tides shift only slightly over that distance, so these times are a close guide for Rehoboth Beach — but treat them as approximate, and for anything safety-related use NOAA directly.
What the tides are like at Rehoboth Beach
Rehoboth Beach sits on the Delaware Bay, where tides run semidiurnal — two high tides and two low tides most days, cycling roughly every 6 hours 12 minutes. The tidal range along this stretch is moderate, generally 4 to 6 feet. For the exact predicted heights and times, read the table and chart above (from the Lewes station).

Where do the Rehoboth Beach, DE tide times come from?
Rehoboth Beach has no NOAA station of its own, so these predictions come from the nearest one, Lewes (Lewes), about 5 miles away. Tides shift only slightly along an open coast, so they're a close guide — confirm with NOAA for anything safety-critical.
How many tides a day does Rehoboth Beach get?
Rehoboth Beach typically gets two high tides and two low tides each day — a semidiurnal pattern. Exact times for today are in the table above.
Where does the tide data come from?
Straight from NOAA CO-OPS, the official U.S. source for tide predictions — for Rehoboth Beach, DE it uses the NOAA station listed above. Heights are in feet above MLLW (mean lower low water, the standard chart datum) and times are shown in the station's own local time.
How far ahead can I see the tides?
Tide predictions are computed from astronomy (the positions of the moon and sun), so they're available about a year ahead. Use the date-range finder to list every high tide between any two dates — for general reference and low-risk scheduling only. Before any marine or shoreline activity, confirm conditions with official local forecasts, alerts, harbor guidance, and NOAA.
What is a king tide?
An informal name for the highest tides of the year, which happen when a new or full moon lines up with the moon's closest approach to Earth. In the finder, the top 10% highest tides in your range are marked with a crown — periods with some of the highest predicted astronomical tides of the year.
What actually makes the tide bigger or smaller?
The engine is gravity: the moon and sun pull the ocean into bulges. When they line up at a new or full moon you get the biggest swings (spring tides); at quarter moons their pulls partly cancel (neap tides), and the moon's closest approach (perigee) super-sizes things further — that's a king tide. River flow, the shape of the bay, and long-term sea-level cycles can also affect the actual water level, which is why real conditions can differ from the astronomical prediction shown here.
What are the highest tides in the world — and in the U.S.?
The world's largest tides are in Canada's Bay of Fundy, where the range between low and high can top 50 feet (it's outside NOAA's network, so it isn't listed here). In the U.S., the giants are Alaska's Cook Inlet — Anchorage sees swings around 26–30 feet — along with Southeast Alaska ports like Skagway, and on the East Coast, Eastport, Maine at roughly 18 feet. All of those have dedicated pages here.
Can I save my home beach and other spots I follow?
