What occurs to the tides during a lunar eclipse?

During a lunar eclipse, the moon passes directly behind the Earth into its shadow. This alignment of the Earth, moon, and sun affects the gravitational forces that influence tides. Normally, the gravitational pull from the moon is a primary driver of high and low tides. During a lunar eclipse, the moon does not exert its usual gravitational force as strongly since it is within the Earth's shadow. As a result, the combined gravitational pull from the moon is slightly diminished.

Because the tidal patterns are influenced by this change in gravitational force, high tides during a lunar eclipse are lower than usual. The effect is due to the fact that the sun's gravitational pull counteracts the moon's, and the blocking of the sun's light also plays a role. This results in less water being pulled towards the moon, leading to an overall decrease in the height of the high tides during a lunar eclipse.
