Miami Beach (Virginia Key), FL tide times

Predictions: NOAA CO-OPS station 8723170 — 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.

Marine-conditions data not available for this station. Wind, swell and water temperature ride along with Open-Meteo Marine; gauge-only stations (e.g. UK EA Flood) publish water level only.

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 Sat 16 May (range 1.2m / 3.9ft). Next neap on Sat 23 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.

Miami Beach reads its tide from the Virginia Key gauge just south of Government Cut, the dredged channel that lets cruise ships into the Port of Miami. The pattern is cleanly semidiurnal — two highs and two lows of comparable size, twelve and a half hours apart. Mean range at the gauge is about 0.7 metres, climbing past 0.9 on spring tides; modest by US East Coast standards but enough to reshape the inside of Biscayne Bay across each cycle. The open beach itself loses 5–10 metres of width on the high and gets it back on the low, a small swing on a sand profile that runs flat and wide. South Beach photographers working the dawn light at low water get firmer wet sand and longer exposed shore than the higher half of the cycle gives. The tidal flow through Government Cut runs harder than the height swing implies, especially on the ebb when the bay drains seaward. Predictions on this page come from NOAA CO-OPS station 8723170. Hurricane season runs June through November, and a tropical-storm surge can stack a metre or more above predicted on top of normal tide; the harmonic table assumes calm.
