Predictions, not observations. These values estimate the tide; they are not measured water levels.
Conditions can change the water level. Atmospheric pressure, unusual wind, storms, and runoff after heavy rain can make actual water levels differ from the prediction.
Station status: This is a subordinate station. Values shown already use this station’s official prediction output; do not add a reference-station offset.
Local time and datum. Times are local to this station and heights use MLLW.
