King tides are expected to return to San Diego's coastline this weekend, thanks to the gravitational forces of the moon and sun.

The interaction between the Earth, Moon, and Sun also leads to spring tides (when the Sun, Earth, and Moon align) and neap tides (when the Sun and Moon are at right angles to each other).

The combined pull of the sun and the moon on the oceans creates spring tides: higher-than-average high tides and lower-than-average low tides. But the moon’s orbit of Earth isn’t a perfect circle.

The WMBF First Alert Weather team gave you the First Alert to Spring Tides this week, which could cause some minor flooding for parts of the Grand Strand.

Learn how Earth's moon formed, how its orbit affects Earth's tides, why solar and lunar eclipses happen and the history of lunar exploration.

Thermal tides in Earth's atmosphere have counterbalanced gravitational tides from the moon, bringing a pause to the slowing down of Earth's rotation.

Discover the fascinating interplay between the Earth, Moon, and Sun that causes the daily rise and fall of sea levels, known as tides. While the Moon's gravitational pull is the primary force ...

The planet’s rotation fluctuates as it travels around the sun, and measurements suggest we’re losing more than a millisecond ...

Typically, times of full moon enhance the tides every month because the sun and moon are in alignment, enhancing their gravitational effects on the tides.

When the spring tide occurs at the perigee of the moon and perihelion of the sun concurrently, the result is the king tide.
