Prediction types
NOAA predicts tides at harmonic stations from each station's own long-term tide record. At subordinate stations, NOAA adjusts the high and low tides of a nearby reference station. YepTidal shows NOAA's predictions for each station as they are and doesn't make the adjustment itself.
