- 'Taku Winds' These winds occur an average of four times a year from October through April in Southeast Alaska. Hurricane force wind gusts (72 mph or greater) occur roughly once every two years during these Taku wind events. Taku winds produce strong wind shear and turbulence that can affect the operation of air transportation in the area. Taku winds can also cause dangerous marine weather conditions. The Taku River, just south of Juneau, was named after the cold t'aakh wind, which occasionally blows down from the mountains.
