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.
Visitors can see 2 extraordinary high and low tides every 24 hours. The time between a high tide and a low tide is, on average, 6 hours and 13 minutes. As such, you can reasonably expect to see at least one high and one low tide during daylight hours. Tide times change, approximately one hour later each day. Tide times also vary slightly for different locations around the Bay.
