What is a king tide?
“King tide” is the everyday name for the highest tides of the year. They come with the new or full moon (spring tides) when the moon is also at its closest to Earth, and they are strongest in the months when the sun lines up too. They are entirely predictable, which is why the dates above are known a year ahead.
