Marazion - surfing
Marazion is quite sheltered so takes a fair old swell to get going. On top of this the prevailing wind is a South Westerly which is onshore. To get any swell into Marazion usually requires a South Westerly gale so most of the time it's onshore.
Perfect conditions are a huge South swell and Northerly winds which does happen every year or so. I've seen Marazion at a solid 4ft and offshore on occasions. However, it is still a fairly weak, slopey wave due to the shallow sea bed. More of a longboard wave really.
There are a few reefs round here that can get good and hold a 6ft+ swell - you'll have to find those yourself though!
