You won’t find many surfers on Alaska beaches, but you’ll find an intrepid cadre of locals who surf the Turnagain Arm bore tide. The bore wave typically shows up after low tide in Anchorage. The largest bores occur during extreme minus tides with the full and new moon cycles. Imagine one wave stretched out like a wide carpet, unrolling in froth as it sweeps into a basin of water. It takes hours for a wave to travel from the mouth of Turnagain Arm all the way to far end. Depending on conditions, the bore can be up to 6 feet tall. Rapidly rising tidewaters are forced up, forming a raised front. These extreme tides hit the narrow, shallow and gently sloping floor of Turnagain Arm. A unique combination of hydrology and geography forms these waves.
