On the water

Fresh water from Lake Union, temperate in summer (16-22°C). Shorty or 3/2 wetsuit in summer, 4/3 in spring and fall. Flat and small waterway, ideal for freestyle. Muddy bottom. Southerly thermal winds at 10-18 knots in summer. The lake is small (0.7 km²), riding space is very limited and shared with many other users.

Hazards

Extremely dense boat traffic: seaplanes (takeoff and landing), recreational boats, sailboats, kayaks, paddleboards, tour boats. Kenmore Air seaplane landing paths are a deadly hazard: absolutely avoid them. Very limited riding space on this small urban lake. Houseboats and docks along the shores. Regulated zones to respect. Winds sometimes irregular and gusty in Seattle's urban environment.
