A King Tide is the non-scientific term used to describe exceptionally high tides. King Tides occur annually and predictably; in September through November in Palm Beach County. King Tides may cause residents to experience "sunny day flooding" where a street or other areas will temporarily become flooded when it is not raining.
Tides occur as a result of the moon's gravitational pull on oceans. The height of tides depend mostly on where the moon is in its 28-day orbit around the Earth and on every 14th day, the moon and the sun line up with the Earth, creating these higher tides. That's why you can expect to see a higher tides on the same day you observe a full moon or a new moon! Some king tides are higher than others based on how close the moon is to the Earth at that time.
Days when we expect the highest tides in 2023 are:
• Days when we expect the highest tides in 2023 are:
• September 29- October 2, expected within three inches of action stage
• October 27-31, expected within three inches of action stage
• November 26, expected within three inches of action stage
Please note that king tides for 2023 are not predicted to reach the action stage or the flood stage, but various factors, including storms, may cause higher-than-expected sea levels and flooding, and that your location may flood at lower sea levels than the NOAA action stage or flood stage.
King tide flooding is not guaranteed during these dates, and sunny-day and other types of flooding, such as rainfall-induced flooding or storm surge, may occur outside of these dates!
