The Moon play a role in weather systems

Tides influence the movement of ocean currents. Warm ocean currents bring warmer, wetter weather, while cold currents bring colder, drier weather.

The El Niño-Southern Oscillation (Enso) may be affected by the lunar nodal cycle too. Usually, strong winds along the equator blow warm surface water westward from South America towards Indonesia. During an El Niño event, these winds are reduced or even reversed and can affect weather worldwide. Usually, wet regions may experience drought, while dry areas may experience rain. A La Niña event will have the opposite effect.
