Guana Bay Surf Guide

Guana Bay on the East Coast is an exposed beach break that is often working. Winter and spring are the best times of year to visit. Offshore winds blow from the west. Most of the surf here comes from groundswells and the best swell direction is from the east. Waves at the beach break both left and right. Rarely crowded here. Be wary of rips - they make surfing here dangerous.
