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.
When the moon and its associated tidal bulges are either north or south of the equator, most points at high latitudes in theory would be impacted by one tidal bulge and would experience one high tide and one low tide per tidal day. This so-called diurnal tide has a period of 24 hrs and 50 min.
