Cape May, NJ 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 19:00 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 Mon 04 May (range 1.4m / 4.5ft). Last neap on Sun 03 May. Next neap on Fri 08 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.

Cape May occupies the southernmost tip of New Jersey where Delaware Bay and the Atlantic meet at the confluence of two distinct tidal regimes. The Atlantic side runs semidiurnal with mean spring range around 1.4 metres; the Delaware Bay side at Cape May Harbour has a larger range reflecting the bay's amplification of the tidal wave — mean springs in the lower Bay reach 1.7 metres and timing differs from the ocean face by 1 to 2 hours. This dual exposure shapes the coastal ecology and the boating environment around the Cape. Cape May is the oldest seaside resort in the United States, and the Victorian architecture of the National Historic Landmark District has been largely preserved. The gaslit streets and gingerbread houses sit three to four blocks from the beach on a low barrier island only a few metres above mean sea level — the tidal and storm surge exposure risk is real. Historical hurricanes (notably in 1821 and 1944) overwashed portions of the island; modern storm surge models show Cape May as one of the more vulnerable points on the New Jersey coast. Cape May Point State Park at the very tip of New Jersey includes Cape May Point Lighthouse (1859, 157 steps to the top), coastal bunker ruins from WWII (steel gun emplacement mounts still visible on the beach), and the hawk watch platform — one of the most famous in the eastern US. The autumn raptor migration (September-November) brings thousands of sharp-shinned hawks, bald eagles, peregrines, and ospreys past the Point daily. The evening roost of monarch butterflies in the trees around the lighthouse in October is among the most spectacular migration concentrations in North America. Sunset Beach on Delaware Bay west of the lighthouse is the traditional diamond-hunting beach — Cape May Diamonds are quartz pebbles rounded by wave action and deposited in the nearshore. Low water spring tides expose the maximum stretch of pebble beach, and the early morning low water period produces the fewest competitors for the best material. The distinctive quartz is found nowhere else in volume on the New Jersey coast. Cape May-Lewes Ferry crosses the mouth of Delaware Bay (17 miles) to Lewes, Delaware in 85 minutes. The ferry timing is not tide-dependent at the dock, but the passage across the bay mouth (one of the most active tidal current zones on the East Coast) is timed by the operators to optimize fuel and arrival window. The Cape May Inlet at the east end of the Cape May Canal connects Delaware Bay to the Atlantic Ocean inside the barrier. Tidal current through the inlet runs to 2 knots on spring tides and the channel is a productive fishing location for summer flounder and weakfish. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
