For contrast: Melbourne Causeway has a range of 0.3 ft — barely a ripple. The 2027 records are computed from a full year of NOAA predictions for 3066 of the 3071 stations.

About this site

Know the Tide serves official NOAA tide predictions for every US tide station — from Eastport, Maine to San Diego, from Key West to Dutch Harbor — with a clean 48-hour curve, a glanceable “tide now” readout, 7-day high/low tables, and a National Weather Service forecast overlay at each high tide. Coverage is NOAA's ocean and tidal-river stations in the coastal states, Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa; the Great Lakes don't have tides, so they aren't here. No account, no clutter. More about the site.
