UH At The Forefront Of King Tides And Sea-level Rise Research

Community groups and media have been relying on University of Hawaiʻi researchers for their expertise in sea-level rise and the state’s record high tides. UH is also seeking the public’s help and involvement.

The UH Sea Grant Center for Coastal and Climate Science and Resilience (Hawaiʻi Sea Grant CCSR), UH Sea Level Center and Pacific Islands Ocean Observing System (PacIOOS) have been tracking high ocean water levels in the region, and are advising that the state likely will continue to experience unusually high tide levels through the summer, in part because of peak astronomic or ”king tides.”

The Hawaiʻi Sea Grant CCSR is asking residents to help document high water levels and related impacts through the Hawaiʻi and Pacific Islands king tides “citizen science” project by submitting photos online. For more information please visit

Community members, businesses, and agencies also are encouraged to regularly check PacIOOSsix-day high sea level and wave run-up forecasts to help increase preparedness and resiliency. Visit for more resources and information on how to get involved.

  1. That these events would occur about now, and get progressively more severe, has been known for about 40 years, and yet we (the State, University, and citizens of Hawaii) are scarcely better prepared for them now than we were then.
