Messages: 357. Slack tide is when the current goes slack between tide changes and slack usually last 30min to an hour after peak high tide or peak low tide(hence high slack or low slack). Feb 27, 2008.
You might think that, because the length of the tide cycle is determined by the Earth's rotation, the tide cycle should be 24 hours long. The reason it's longer is that, during a 24-hour period, the moon travels about 12 degrees of its 360-degree orbit.ou might think that, because the length of the tide cycle is determined by the Earth's rotation, the tide cycle should be 24 hours long.
