Timetable of seaside low tide in 2022

The timetable for going to sea at low tide in 2022 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.

The law of high tide and low tide of seawater is: the tide rises twice a day, with an interval of 12 hours. The high tide usually lasts for more than an hour, and the low tide begins, and the lowest tide is between the two high tides.

Calculation principle:

Suppose: today is the fifteenth day of the lunar calendar, and the high tide time is = 15×0.8= 12, that is, noon 12 and midnight12; The lowest ebb time is 6 am and 6 pm. Close observation time is from 4 am to 8 am and from 4 pm to 8 pm.

Therefore, the climax of the next day is 0.8 hours (48 minutes) later than the previous day, and the daily climax time can be calculated according to the lunar calendar date. The specific calculation method is: if the number of days is less than 15 days, directly multiply the number of days by 0.8 to get the highest high tide time of the day; If the number of days is greater than 15 days.
