Miami Beach (Virginia Key), FL tide times

The hero block above shows the next high tide at the Virginia Key gauge in local Eastern time, height above MLLW. The 7-day table below covers all four daily extremes. Government Cut, Haulover Inlet to the north, and the Port of Miami all read the same gauge with phase differences under 15 minutes.

Mean range at Virginia Key is about 0.7 metres. Spring tides — around new and full moons — push to roughly 0.9 metres, neaps drop to about 0.5 metres. The Florida East Coast runs a smaller swing than the Carolinas or New England because the open Atlantic forcing isn't funnelled by a continental shelf the way Massachusetts Bay or the Bay of Fundy approaches are.

NOAA CO-OPS station 8723170 at Virginia Key, just south of Government Cut. NOAA computes harmonic predictions from a long historical gauge record at this exact location. The result is navigation-grade accuracy under normal weather. Hurricane storm surge during named storms overrides the harmonic signal completely; the National Hurricane Center is the authoritative real-time source then.

South Beach gains 5–10 metres of width at the daily lower low. The widest, firmest walking surface is the hour either side of low water, and the swing reads largest on the spring tides around new and full moons. The 7-day table flags each day's lowest predicted tide; pair with the sunrise time on the sun/moon block for a dawn beach run on hard sand.

No. For piloting in or out of Government Cut, Biscayne Bay, or the ICW use NOAA's authoritative chart products and the latest USCG notices. Cruise-ship traffic, the dredged main channel depths, and the strong currents through the Cut on the change of tide need real navigational sources, not a planning tool.
