For surfers, tides can be a crucial factor, one of many – including winds, swell direction, et al – which determine whether or not a wave is good or not at any given time. And different places have different tidal ranges. It’s all very heady stuff, science-heavy matters involving the moon, gravity, inertia, and all sorts of features that a layperson may not quite understand. But it’s still interesting. And one place where the tides are so extreme is the Bay of Fundy in Canada. Above, watch just how drastically the tide changes throughout the day at this Nova Scotia location. According to PBS, who documented the phenomena: “Where typical ocean tides average about three feet, the Bay of Fundy’s record-setting tides soar over 50.
