Guia de Isora

Guia de Isora is an SW-facing reef break in Playa San Juan, Canary Islands, Spain. It picks up swell from S to WSW and NW to NNW, and land, islands, reefs or shallow banks block about 56% of the directions it faces. Offshore wind here blows from the NE: light winds or NE breezes usually mean the cleanest surf, while SW onshores chop it up.

Rare slot: a Canary Islands gap lets in swell from 285.2° (WNW) and nothing either side. It only lines up when a storm sits in that exact direction, more than 102 km out. How slot swells work
