> Predicted high and low water for 218 US coastal places, each joined to the NOAA CO-OPS tide-prediction station that covers it, with that station's distance, datum and mean tidal range.

## Key facts

- 289,435 predicted high and low waters across 218 US coastal places, read 2026-09-10T00:00:00Z.
- Every table names the NOAA CO-OPS station it came from and how far that station is from the place, because a tide table is the station's water and not the beach's.
- Heights are feet above MLLW (mean lower low water), which is why a low water can read below zero. These are predictions, not observations, and none of it is for navigation.

- 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.
