where such a bore tide forms. The bore tide is a phenomenon that occurs because the Turnagain Arm inlet is shallow, narrow, and long. It’s such a long inlet that the tide that’s going out collides with the surge of the new tide that is coming in and that creates a surf wave.
Is the bore tide dangerous?

This means your chances for seeing a large bore are best during the five-day window that surrounds the new and full moons. Get the dates for new and full moons from the NOAA site. During this window, get the times for the two Anchorage low tides occurring each day either from tide charts available at gas stations or in the table below.
