What we look for at Mussel Rock (The Dumps)

The wind must blow from within this arc. Direction is the same for both wings.

Coastal ridge soaring; ideal due W, light SW OK. Upper cliffs amplify wind to 20+ mph when 12-13 below. Hazards: blowback into Westlake powerlines/houses, ocean landings (fatalities). SFO ultralight ceiling 1600ft. Unregulated, popular. Cheetah launch=SSW-WSW, advanced/south days.
