Many scientists believe that tides have a small influence on the weather. Tides can have some effect upon ocean currents, for example, which, in turn, influence weather patterns. It is also known that the Moon’s tug on our planet can actually cause measurable changes in topology (the Earth’s crust actually moving up and down). This can, in turn, encourage earthquakes or volcano eruptions, and the latter definitely affects our weather. Tides, it can be said, may also be relevant to weather because, when strong onshore winds coincide with high tides, coastal flooding is made worse than would otherwise occur at low tides.
