How to check the schedule of ebb and flow?

To check the schedule of high tide and low tide, you can check the local tide table.

The following is a detailed explanation:

1. What is a tide table?

Tide table is a table or chart that lists tide height and forecast time. It is usually used for sailing, fishing, swimming and other activities.

2. How to get the local tide table?

There are many ways to get tide tables: search for the keyword "local tide table" on the Internet, and you can find many websites specializing in tide prediction. Get a printed tide table from the local maritime bureau or tourism bureau. Download the local tidal forecast APP.

3. How does the tide gauge work?

Tide prediction is based on the attraction of the moon and the sun to 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 the 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 mark the following situations: the high tide mark is "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 height of the tide is the smallest, which is called "small tide".

5. What is the importance of tide tables in navigation, fishing and other activities?

Tide tables are very important for some activities that need to consider the height and time of tides. For example, navigation needs to consider the depth of water, and fishing needs to choose the right time. Therefore, knowing the local tide table can help us to carry out these activities better.

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 usually 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 the tide in the morning and the 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.
