High tide and low tide schedule

First of all, the tide rises and falls twice a day, and the tide rises and falls at different times every day.

1, the schedule of the ebb and flow of the tide is based on the lunar calendar, which is very important. Many guests don't know this, so the checkout must be wrong.

2. The time when the tide begins to rise is the lowest, and it starts to rise from this point, and it rises higher and higher.

Calculation method of tide:

High tide: the first half of the lunar calendar, that is, the first day to the fifteenth day, and the morning is the day of the day × 0.8; The high tide time in the morning plus 12 hours and 24 minutes (12.4 hours) is the high tide time in the afternoon. In the second half of the month, just subtract 15 from the days of the lunar calendar, and then calculate according to the previous formula.

There is a formula to calculate the ebb and flow of the tide: two jobs a day on the eighth day; The first day and the fifteenth day, two whole days.

For example, on the eighth day of the lunar calendar, the time of high tide in the morning is 8 × 0.8 = 6.4, which is 6: 24; Afternoon: 6.4+ 12.4 = 18.8, which is 6: 48 pm. Seashells can be caught in Rizhao coastal area from two hours after low tide to about one and a half hours after high tide.
