The Guillotine Surf Guide

The Guillotine in the Margarets River Area is an exposed reef break that has very consistent waves, although summer tends to be mostly flat. Offshore winds are from the east northeast. Tends to receive distant groundswells and the ideal swell angle is from the southwest. A reef breaks left. Best around mid tide. Unlikely to be too crowded, even when the surf is up. Take care of rocks, sharks and isolation.
