Source: Tide predictions and station data from NOAA CO-OPS (tidesandcurrents.noaa.gov), read 2026-09-10; US Government work, public domain (17 USC 105). Heights are feet above MLLW (mean lower low water); times are the station's own local clock.

Methodology: One row per US place a measured tide query names, joined to the nearest NOAA CO-OPS tide-prediction station within 45km and carrying that station's distance, because the reader is owed the fact that the table is the station's and not the beach's. Heights are feet above MLLW; a subordinate station publishes no datums, so its means are computed from its own predictions. Predictions are PREDICTIONS: weather, atmospheric pressure and river flow move real water levels away from them, and none of it is for navigation.
