Tidal forecasting is based on the gravity of the moon and the sun on the earth's tides. Due to the change of the relative position of the moon and the sun, the tides and tidal heights will change every day. Therefore, the tide table will list the tide height and corresponding fluctuation state at each time point of the day.
4. What do the marks in the tide table mean?
Usually, the tide table will be marked with the following conditions: the high tide level is marked with "H" or red. The low water mark is "L" or blue. The height of the tide is the highest at the full moon and the new moon, which is called "spring tide". On the contrary, when the moon is in the first or third season, the tidal height is the smallest, which is called "small tide".
5. What is the importance of tide tables in sailing, fishing and other activities?

High tide is a natural phenomenon. There are high tides and low tides in seawater. At high tide, the sea rises, the waves roll and the scenery is spectacular. At low tide, the sea receded quietly, revealing a beach. High tide and low tide are generally twice a day.
The fluctuation of sea water is called tide during the day and sunseeker at night, so it is also called tide. China's ancient book says, "The sea is a tide in the morning and a sunseeker at night". There is a period between high tide and low tide when the water level does not rise or fall, which is called flat tide.
