As water flows out of Turnagain Arm, the tide changes and water starts to flow back into the arm. The opposing water flows meet, creating a wave that travels up the arm with the rising tide.

The wave can reach 6 to 10 feet as it travels up the shallow arm. If the wind is blowing out the arm, as it often does, it will push the wave higher in the narrowing arm.
