For a few months of the year (July-Oct) there is surf enough to get novices and experienced surfers out on their boards. We are not talking Waikiki but certainly worthwhile.
Both ends of Surin beach are good for surfing, although you need to be aware that there’s a rock formation in the central part of the beach, visible at low tide. The northern end of Surin Beach there is a rock formation which sometimes creates a small sandbank resulting in a fast and short wave to ride. The central part of the beach also has a sandbank which creates a nice break at mid tide. The sand bottom all along the beach (apart from its extremities) assures a safe landing.
If you are looking for another activity in the green season then perhaps this is it!!
