Each month, the highest tides occur during the full moon and new moon, as the Sun, Earth and Moon are in alignment. But, during the Earth’s annual trip around the Sun, it is the closest around the winter solstice.
As a result, the pull of the Sun on Earth’s gravity is the most, and with the full moon, the combined effect makes for the highest tides of the year producing the King Tides.
If along the coast this weekend into next week, take care if near the surf zone, as tides will be higher than normal.
