There is a surf school at Saltburn too – easy drive up the A19. The one at Cayton Bay is linked to Secret Spot Surf Shop who have always been really helpful when I used them – but I’ve no experience of either surf school.
I would speak to them to see what they offer and then pick what seems the best value. The key thing is to see how quickly they will get you out of the white water and into trying for the green waves. I would also check what happens if its flat in terms of refund, rescheduling or whatever – it can be flat for extended periods over the summer.
Other than that I would not bother with too many lessons – once you know what you are supposed to be doing its then pretty much about just getting as much water time as you can so your body can learn it.
BTW I surf out on the East coast quite regularly, it isn’t that much of a pain from West Yorks as you might think. May see you out there…
