Middles

Isabela, Puerto Rico
🪸Sharp reef⚠️Shallow😮‍💨Hold-downs

Middles is Puerto Rico's most challenging wave—a fast, powerful reef break that delivers Hawaiian-style barrels on the north coast. The wave breaks hard and fast over shallow reef, demanding commitment and experience. When overhead swells arrive, it's a serious proving ground that separates the locals from the visitors.
