King Tides Flooding
In short
King tides are exceptionally high tides that occur when the moon and sun align, causing significant coastal flooding. As of late October 2026, record-breaking tides are swamping both U.S. coasts, with water levels in some areas exceeding those seen during historic hurricanes.
In plain words
These tides happen when the moon is closest to Earth during a full or new moon. The extra gravitational pull drags more water towards the shore. This can flood streets, erode beaches, and trap residents in coastal towns.
A simple example
In West Palm Beach, king tides have recently flooded Flagler Drive, forcing officials to warn drivers to stay away from the submerged roads.
Why it matters
They cause serious damage to infrastructure and property without the need for a storm. As sea levels rise, these natural events become more dangerous and frequent for coastal communities.
Easy to mix up
Do not confuse king tides with storm surges, which are caused by wind and pressure during hurricanes.
