This is precisely why I brought the subject up!!
Padstow harbour opens out to an estuary, the estuary can be completely flat water & to anybody who does not know the area they would assume it to be perfectly safe looking, it has beautiful clear waters too most of the year, frequent Dolphin sightings etc. The estuary opens into Daymer bay which opens NW is fully exposed to any prevailing swell that can come from the Atlantic.
I have been there windsurfing with a 5-8m swell (that is the massive!!!) coming through & down the estuary it can be epic because of the funnelling effect, a bit like the Severn Bore.
However trust me on this, you can be near the Doombar to the south of the estuary near the old lifeboat station, on an incoming tide in perfectly flat waters & get totally swamped from a wave that appears with seconds as it nears the shallows. Even in completely flat waters with no wind you can get massive waves appearing from nowhere.
Wkipedia: For centuries, the Doom Bar was regarded as a significant danger to ships—to be approached with caution to avoid running aground. It has accounted for over 600 beachings, wrecks and capsizings since records began early in the 19th century,
with about 300 being wrecks.
Check out this filmed at Daymer Bay/Doombar it kind of shows what I'm on about Daymer Bay on Vimeo
This image shows the sandbar that is exposed at low tide, there have I think been hundreds of shipwrecks on it.
