Waverly has the best water conditions on Lake Washington ... why do you think it's called WAVErly? It can be sailed on anything from a SE to a SW push with dead south forming the best waves. The 20 mile uninterupted wind path down the lake creates the occasional 6 ft face. 70 mph winds are clocked each year on my annemometer at my perch above Juanita Beach (which you can downwind sail to if you can find a buddy to pick you up).

You will always find someone to sail with if there is any wind to speak of. Both parking lots will be jammed if it's sunny 5.0.
