You can find it in two ways: search for "China Maritime Network" on the computer webpage, and add the "Ocean Weather Tide Query" applet on the mobile phone WeChat:

1. Use computer search to open the webpage "China Maritime Service Network-Tide Table" (ocean.cnss.com.cn/), and customize the port name and date.

2. Search for the "Ocean Weather Tide Query" applet on the mobile phone WeChat, click Enter, select "Tide" and enter "Tianjin" to query.

Extended data:

High tide refers to the natural phenomenon that the ocean surface rises regularly under the gravity of the moon and the sun. In the tidal cycle, the tidal level changes from low tide to the next high tide. Because the day is morning and the night is evening, the fluctuation of sea water during the day is called "tide" and the fluctuation of sea water at night is called "sunseeker".

Low tide refers to the process of sea surface falling during the transition from high tide to low tide. Low tide is also related to the interaction between the moon and the sun. When the sea surface drops to the lowest position, the sea surface will be in a short-term equilibrium state and the tide will stop.

The fluctuation of seawater has certain natural laws. There is a way to calculate and master the time of daily tidal fluctuation. Take Qingdao, Shandong Province as an example, the waters near Qingdao are regularly semi-diurnal tides. According to this calculation, each tidal activity cycle is a little more than 12.4 hours, and there will be two fluctuations in one day. In other words, the daily ebb and flow time is about 0.8 hours later than the previous day. Mastering the law of tidal fluctuation time has brought great convenience to the daily production and life of people in coastal areas.

People's observation of the ebb and flow of the tide sums up two daily high tide formulas: from the first day to the fifteenth day of each month, (lunar date-1)×0.8+5(0 o'clock); Every month 16 to the end of the month is (lunar date-16)×0.8+5 (points). Using the above two formulas, we can calculate when the tide is high in a day, and then push it back for 6.2 hours to be low, and then the interval of 6.2 hours is the high tide time. Tidal fluctuation time varies from place to place, mainly due to the difference of lunar calendar date, local tidal type and longitude. We can observe the local tidal law carefully and calculate with reference to the above formula, and then we can roughly get the local tidal time.
