Lake St. Clair Tides
Great Lakes: Tiny Tides, Big Changes Do the Great Lakes have tides? Technically, yes, but they're so small they're hardly noticeable. The gravitational pull of the sun and moon does create tiny, twice-daily changes in water level, but these are less than five centimeters at their peak. What really drives water level changes in the Great Lakes is weather. Wind and barometric pressure can significantly alter lake levels, making these much larger fluctuations seem like tides. Additionally, long-term weather patterns, seasonal changes, and even short-term storms can impact water levels. Another factor often mistaken for tides is a seiche, a large wave caused by wind pushing water to one end of a lake.…
