The biggest waves can reach a height of up to 12 feet, although this is a rare occurrence and is only seen during June, July and August.

The beaches in the area are generally clean and recent efforts by the government and local business organizations are proving themselves. While the beach has not regained its Blue Flag Status, in September 2008 it did get a clean bill of health from the Costa Rican government. The town is trying to regain its Blue Flag Status.
