Local Knowledge & Surf Guide
Local Knowledge
Avellanas Rivermouth is an exposed sandbar break in Guanacaste that offers fairly consistent left and right-hand waves. The most favorable conditions are a south groundswell with offshore winds from the west. When the surf is up, crowds are likely, and surfers should be aware of dangerous rips. The best time for consistent, clean waves is typically in September.
