Data interpretation & safety

Weather-buoy and tide-gauge values are observations; tide times and tide curves are predictions. Observed water level can differ from astronomical tide because of weather and other conditions. Data can be delayed, unavailable or revised and should not be used as the sole source for navigation, emergency decisions or personal safety.
