The following table shows the time of day when tides occurred at a coastline on a certain day of a year.

Coastline Tide Table

Date Time Type of Tide

Sunday, 4th June 2:31 a. m. Low tide

8:35 a. m. High tide

Predict the approximate time when the next high tide and the next low tide would occur at the same coastline.

Explain your answer.

Tide has a periodic cycle and is usually every 12 hours 25.2 minutes; exactly half a tidal lunar day. It also varies over the lunar cycles and the costal location. But within the same day and same location, the cycle time is pretty stable.

You can find the next high and low tide by forwarding 12 hrs 25.2 mins; which gives 9pm and 2:56pm as time for the next high and low tide.

Tidal cycle is typically about 12 hours and 25 minutes.

adding that to the given data, the next low tide will be 2:56 pm and the next high tide will be 9:00 pm.
