Tides and weather

On the Atlantic side, the strait is characterized by semidiurnal macrotides with mean and spring tide ranges of 7.1 and 9.0 m, respectively. On the Pacific side, tides are mixed and mainly semidiurnal, with mean and spring tide ranges of 1.1 and 1.2 m, respectively. There is enormous tidal energy potential in the strait. The strait is prone to Williwaws, "a sudden violent, cold, katabatic gust of wind descending from a mountainous coast of high latitudes to the sea".
