Record-Level King Tides Continue Through Memorial Weekend
Coastal flooding impacts associated with record-level “King Tides” will continue each day along all shores through the Memorial Day Holiday weekend. The National Weather Service says beaches and shorelines, boat ramps and docks, and vulnerable low-lying roads and structures will be impacted by coastal flooding through the late afternoon and early evening hours.
The following are the daily forecast tide levels and times for various locations throughout Maui County which will correspond to coastal flooding impacts. Be advised that observed tides have been running much higher than these values.
Kahului Harbor:
5/27 Saturday 4:31 p.m. 2.73 ft
5/28 Sunday 5:20 p.m. 2.59 ft
5/29 Monday 6:13 p.m. 2.40 ft
Hāna:

In addition to the coastal flooding impacts, a long-period south-southwest swell will continue to generate elevated surf along south facing shores into late Sunday. Therefore, a High Surf Advisory remains in effect for south facing shores of all islands through Sunday afternoon.
The combination of large surf and high water levels will result in additional wave run up along south facing coastlines, likely flooding beaches that typically remain dry and exposed during typical high surf events along southern shorelines.
Surf heights and water levels are forecast to gradually trend back toward normal values early next week.
Ocean models generated by the University of Hawai‘i Sea Level Center indicate that elevated water levels are likely to persist through the summer. According to the Hawai‘i Sea Grant Center for Coastal and Climate Science and Resilience program, record high water levels are expected around the upcoming highest astronomic tides of the year, known as “king tides,” occurring over a few days around the new moons on May 25-26, June 23-24, and July 21-22 in Hawai‘i.
