Predictions: NOAA CO-OPS station 8534720 — heights relative to MLLW.

Harmonic prediction from the official tide authority. Very high accuracy under normal conditions; storm surge may shift actual water level. Not for navigation.

Next spring tide on Fri 01 May (range 1.4m / 4.7ft). Last neap on Sun 26 Apr. Next neap on Thu 30 Apr.

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.

Atlantic City sits on Absecon Island on the New Jersey shore about 100 kilometres south of Manhattan, fronting the Atlantic on the long barrier-island chain that runs from Sandy Hook in the north to Cape May at the Delaware Bay mouth. The boardwalk has been in continuous service since 1870 — the first elevated wooden promenade ever built — and the eight-block beach widens by 20 to 30 metres at low water along the central Steel Pier and Boardwalk Hall stretch. The tide here is a moderate semidiurnal signal that the open Atlantic delivers cleanly to the New York Bight: mean range at the Steel Pier gauge is about 1.3 metres, with two highs and two lows of comparable size about twelve and a half hours apart. Spring tides push close to 1.6 metres and neaps drop near 0.9. The barrier-island geometry concentrates tidal exchange through narrow back-bay inlets — Absecon Inlet at the northern end of the city separates Absecon Island from Brigantine and runs sharper currents than the open-coast height swing implies, and the Beach Thorofare network of marsh creeks behind the city drains and refills on every cycle. The fishing-pier culture at the Steel Pier (the original 1898 pier where Frank Sinatra and Frank Sinatra Jr. both opened summer residencies and where the diving horse used to plunge from the high platform), the salt-water-taffy boardwalk tradition that Joseph Fralinger and James Salt pioneered in the 1880s, and the working clam fleet operating out of the Atlantic City and Cape May docks all read the table for different windows. The defining hazard is the combination of nor'easter and post-tropical surge events. The Ash Wednesday storm of March 1962 cut new inlets through Long Beach Island just to the north and stacked water four metres above predicted at Atlantic City; Hurricane Sandy in October 2012 ran a 2.7-metre surge that destroyed sections of the boardwalk and reshaped the beach profile from Atlantic City through Seaside Heights. The post-Sandy beach replenishment programme rebuilt the protective dune system that the modern city depends on.
