Surf: Octagon and the empty beachbreaks to the north like Boilers, may yield a slightly faster, hollower wave in E-S swells with lots of room for the scores of longboarders who congregate in their 4X4s on the beach. Environment: It's a bit more consistent than Galveston but more polluted water flows from the Brazos River. Named after a has that got swept away hence Octagone.
