Yes and yes. Cold water (winter suit 6/5/4, summer suit 4/3) and you do need to be aware of the posibilty of dead heads in the water. However the probability is low. Much more likely is the
new surfers in the water closer to shore learning to surf with one of the many surf schools. No sharks and few rocks just sand. Great picture of the surfer and the log! This is an interesting video that has likely been shown before. It is from Ucluelet just down the road from Tofino. A bit more exposed, lots of rocks and in the video a pod of Orcas hunting seals in the lineup!
