The pattern is WAY longer than weekly, because you have both the Lunar (12.4 hours) and the Solar (12 hours) tides, plus the distance between the Earth and moon and the Earth and the Sun constantly vary.Wow, who would've thought it was a weekly pattern?
Canada RAM, is there anything you don't know?CanadaRAM said:Technically, you have both a high and a low tide each morning (midnight - Noon) and a high and a low each afternoon.evening (Noon- Midnight) but since the lunar cycle is not an even 12 hours, the cycle time creeps around the clock

Because of the local sea depth and geography, the height, lag behind the moon, and interval between tides is different at every location on Earth.
Where I work we resell tide data, (among other things) Every year we buy a CD from NOAA with a years worth of data and then digest it for republication.MacNut said:There really isn't a pattern, It is constantly moving. A high tide today will be about 45 mins later tomorrow. So lets say you wake up at 8 am and the tide is high. If you wake up at 8 tomorrow the tide will have another 45 minutes before it is at its highest point.
The tides cycle 4 times in a 24 hour period. High then low then high then low, each 6 hrs and 12 minutes apart.
So if its high at 8:00 am it would be low at 2:12 pm then high at 8:24 pm and low at 2:36 am and high at 8:48 am
