Moon influence and forecast source
Neap Tide — Moderate tides with smaller range. Good for calm beach activities.
Heights in meters above chart datum. “Mean level” is the average of this day’s extreme heights; it does not indicate depth.
We calculate tides using FES2022 harmonics and calibration data from FEMAR reference stations. Heights use the model’s reference-station baseline, not measurements at each village. For rivers and inland locations, the curve is a coastal tide reference; it does not predict local water levels.
