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.
To put this in simple terms the large tides caused by the linear alignment of the sun, earth and moon are called spring tides and occur at two week intervals corresponding to new and full moons. Neap tides also alternate at two week intervals and occur when the earth, moon and sun form a right angle. This will happen during the first and last quarters of the moon phases. Now if you have ever looked at a tide chart and wondered why there is a slight difference between the tides on one day to the next.
