Why are the low tide time and tide level, and the high tide time and tide level I find in a newspaper or on the web different from those indicated by the watch?

Actual tidal phenomena fluctuate in accordance with weather, the season, and various other factors, and may give rise to irregularities not in accordance with calculated values. Certain conditions may result in actual tides being different from calculated data.
Because of this, the information produced by the Tide Graph function of this app and watch should be treated as approximate reference information only. Never use this information for any decisions about tide that may put safety at risk. For navigation purposes, be sure to use official tide charts for the area you are navigating.
