Tidal table in Zhimiao Bay

Zhimiao Bay, also called Dongdaihe area by many people, is located on the edge of Bohai Sea in Huludao. It has a unique climate and natural ecosystem, and there are almost no traces of pollution caused by human civilization activities. It is still a pure land. Let's introduce it in detail below.

Query on the Year of Tidal Table in Dongdaihe River

The fluctuation of sea water is called "tide" during the day and "sunseeker" at night, so it is collectively called "tide". China's ancient book says that the sea water is born as a tide in the morning and a sunseeker at night. Its occurrence is related to the sun and the moon, and also corresponds to the traditional lunar calendar in China.

The tide level rises to the highest at 6:00 am and 18:00 pm on the first and fifteenth day of each lunar month, and drops to the lowest at 12:00 and 0:00 am. Then the time of high tide and low tide every day is delayed by 48 minutes.

There are two orgasms every day, with an interval of 12 hours. The high tide generally lasts for more than an hour before the low tide begins, and the low tide time is at least between the two high tides.

The time of high tide is different every day, and the period is 15 days. Therefore, the climax of the next day was 0.8 hours (48 minutes) later than that of the previous day. The daily high tide time can be calculated according to the lunar calendar date, and the calculation formula is as follows:

The first to fifteenth day of the lunar calendar: high tide time = date *0.8.

Lunar calendar 16 to 30: high tide time = (date-15*0.8)

Note: Everything needs to be safe. Don't go near the sea at high tide. This is very dangerous. Adults should pay attention to their children's movements and stay away from the sea.
