Ostia

Ostia is an SSW-facing beach break in Roma, Lazio, Italy. It picks up swell from S and SSW to SW, and land, islands, reefs or shallow banks block about 92% of the directions it faces. Offshore wind here blows from the NNE: light winds or NNE breezes usually mean the cleanest surf, while SSW onshores chop it up.

Rare slot: the Strait of Bonifacio lets in swell from 261.8° (W) and nothing either side. It only lines up when a storm sits in that exact direction, more than 254 km out. How slot swells work
