Does the sea have a high tide time?

The daily schedule of high tide and low tide is: the high tide and low tide of seawater have certain rules, and the tide level rises to the highest at 06:00 am and 18:00 pm on the first and fifteenth day of the first lunar month, and drops to the lowest at 12 and 00:00. Then the time of high tide and low tide is delayed by about 48 minutes every day.

The seaside is a good place for swimming and leisure in summer. Before swimming, we must know the weather first, and the time of tidal fluctuation at the seaside is very important.

Generally speaking, 2 hours before the high tide and 1 hour after the high tide are more suitable for swimming, because people will not be washed away when the tide reaches the shore. At this time, the water quality is also the best. Swimming is not recommended at low tide, because people are easily carried out by the tide and the water quality is generally poor at low tide.
