With limited interference from any outside sandbars and/or coquina reefs, which are famous for intercepting or diluting swells in the Sunshine State, Main Beach can offer a legit shorebreak experience at higher tides; which means when it’s good here, it’s a bonanza: lots of waves, most of them hollow and fast and powerful, and the crowds to match. Reeling lefts manifest on the best NE swells, however, Amelia Island beachbreaks in general are exposed to a range of swells from N to S but won't hold more than a couple feet overhead.
