There are some other islands in the Caribbean but perhaps the best one to learn to surf on is Barbados.
You have some really easy spots to learn and you probably will be able to stand up on the first lesson. Freights bay if the swell is good enough produces a nice clean left hand wave that is very gentle on the debutant.
If you want to see how good Barbados surfing gets then here is Soup Bowl on a good day
I really like that there is some positive aspect of hurricane's !!! In this case Hurricane Igor sends a grand swell to Barbados
