The bore tide is a huge wave or series of waves that advance down Turnagain Arm in a wall of water up to 10-feet high. It’s a dramatic show of nature’s power that’s easy to see using our guidelines below.
Bore tides can stretch half way across the Inlet
The bore tide is a rush of seawater that returns to a shallow and narrowing inlet from a broad bay. Bore tides come in after extreme minus low tides created by the full or new moon.

Tidal bores occur on Turnagain Arm every day, but most produce relatively modest waves. In theory, you would expect the largest bore tides to occur on tides with the highest tidal differential. In reality, they tend to occur just before or after that. This means your chances for seeing a large bore are best during the five-day window that surrounds the new and full moons. Extreme low tides promise the largest bores because of the amount of water rushing back into the inlet. Also, tides tend to be greatest annually at the equinoxes (March and September), particularly during the fall equinox, so look for especially strong bore tides if you’re traveling then.
