![]() Get the dates for new and full moons from the NOAA site. This means your chances for seeing a large bore are best during the five-day window that surrounds the new and full moons. In reality, they tend to occur just before or after that. In theory, you would expect the largest bore tides to occur on tides with the highest tidal differential. Tidal bores occur on Turnagain Arm every day, but most produce relatively modest waves. Hope, a town across Turnagain Arm, but it's a good 100-mile drive from Anchorage and takes a little under 2 hours to get there.Bird Ridge, about 30 minutes south of town, where you can get a wider but more distant view.The highway traverses the shoreline along the flats, giving you a real sense for the power and scale of the bore tide. There are five highway pullouts along this stretch. The best viewing is from there all the way down to Portage, about an hour south of town. Beluga Point, a 20-minute drive south from Anchorage.Plus, it's a wildlife-spotting opportunity: harbor seals often ride the tide into Turnagain Arm, and beluga whales may come in a half hour or so later once the water gets deeper to feed off fish that come in on the tide. It's amazingly accessible: you can see it by road along its entire 40- to 50-mile length along Turnagain Arm near Anchorage. ![]() Beluga whales may come in a half hour or so later once the water gets deeper. And it’s a wildlife-spotting opportunity: harbor seals often ride the tide into Turnagain Arm. It’s also amazingly accessible: you can see it from the Seward Highway along its entire 40- to 50-mile length. The Turnagain Arm bore wave is the only one that occurs in the far north and the only one bordered by mountains, making it the most unique and most geologically dramatic bore tide in the world. Also, all other bore waves run up low-lying rivers in more southerly latitudes. Well, it’s huge- one of the biggest in the world, actually. Read and see imagery from photographer Jeff Schultz's first-hand account of seeing the bore tide What's So Special About the Turnagain Arm Bore Tide? The Thrill of Witnessing A Bore Tide along Turnagain Arm It takes not just a low tide but also about a 27-foot tidal differential (between high and low tide) for a bore to form in Turnagain Arm. ![]() It builds up to 6 – 10 feet tall and can reach speeds of 10 to 15 miles per hour. Alaska’s most famous bore tide occurs in Turnagain Arm, just outside Anchorage. One in China, for example, stretches almost 30 feet tall and travels more than 20 miles per hour. Bore tides come in after extreme minus low tides created by the full or new moon.īore tides occur all over the world-there are around 60 of them-but only a few are large enough to make a name for themselves. The bore tide is a rush of seawater that returns to a shallow and narrowing inlet from a broad bay. You can easily see this dramatic show of nature’s power from the Seward Highway using our guidelines below. The bore tide is a spectacular sight, a wave up to 10 feet high, that thunders into Turnagain Arm just south of Anchorage in the right tide conditions.
