PBS · October 3, 2026Original source ↗
What happened
Kelvin waves are large water bulges that occur in the ocean, causing fluctuations in sea level as they travel along the coast. Unlike tsunamis, they do not break or crash onto shores but instead function more like water sloshing in a contained environment. These waves can affect coastal sea levels temporarily.
Why it matters
Understanding Kelvin waves is important for monitoring and predicting changes in sea level that could impact coastal communities.
