TIDE OBSERVATIONS

• A tide prediction is NOT the same as the actual tide that occurred. Predicted tidal heights are those expected under average weather conditions. When weather conditions differ from what is considered average, corresponding differences between predicted levels & those actually observed will be noted. Generally, prolonged onshore winds or a low barometric pressure can produce higher levels than predicted, while the opposite can result in lower levels than predicted.
