The following information is for reference only. You are advised to plan your own dives and cross reference the data you use. Slack times are closest to what has been used by skippers for years but also depend on the state of the tide and various other factors.

Check out the Portland Tide Times before your visit and for planning. We advise you take into account differences relating to exact location (i.e. east, west side of island, the cove etc.) as well as the state of tides (neap vs. springs) when calculating approximate slack windows. Maximum depth on deeper sites may vary according to the state of tides.

Plan your own dive and slack times on the date of the dive. The information is best used together with the Portland Tidal Streams Atlas and annual Tide Tables. The links below open in a new window.
