King Tides Trigger Widespread Flooding on US Coasts
Unusually high tides, exacerbated by a full moon, are causing significant flooding in coastal communities across the United States.
Coastal communities on both the East and West Coasts are experiencing significant flooding as exceptionally high tides, known as king tides, coincide with a full moon. The phenomenon is leading to widespread inundation of low-lying areas, impacting daily life and infrastructure.
In Long Beach, California, residents are contending with massive waves and overflowing waterways. The elevated water levels are a predictable, yet disruptive, consequence of the gravitational pull from the moon and sun aligning during a full moon, amplifying tidal forces.
These king tides occur periodically and are often a topic of discussion for coastal city planners and residents concerned about sea-level rise. While these events are natural, their increasing severity and impact are frequently linked to broader climate change trends that are causing sea levels to rise globally. The flooding reported on October 27, 2026, highlights the vulnerability of coastal regions to these amplified tidal events.
