How to Calculate Bore Tide Arrival
The bore tide wave occurs daily, roughly 2 hours and 15 minutes after low tide in Anchorage. Check the Anchorage low tide table, add the time offset for your target viewing pullout, and arrive at least 30 minutes early.
Extreme Tide Coefficients
The bore tide wave is largest during 'spring tides' (new moon and full moon phases) when the tidal coefficient is highest. During these periods, the wave front can rise 6 to 10 feet tall, drawing surfers and kayakers from around the world.
Bore Tide Schedule Verification
Always cross-reference tide tables with official NOAA tide predictions for Turnagain Arm (specifically the Sunrise Station or Bird Point tables) before driving out.
