Spot Details

Wally's Beach, 45 min SW of Lethbridge near Cardston is an option in the extreme south of Alberta. Grass and sandy rigging, relatively cool water, and an extremly picturesque setting near the mountains. West winds produce a superb onshore ocean-like ridable 2m wave break over rock reef when water is high in late spring and winds blow over 60 km. The launch is a little sketchy with a kite (onshore with big trees) ... it is better for kiting when the water level is low.

Simply huge waves when the Chinooks are howling.

Water levels can be an issue.
