WAIKIKI, Hawaii - Scientists from the University of Hawaii's Sea Grant Program have been monitoring King Tides since 2015 and said the two or three biggest tides of the year in Hawaii, gets the King Tide label. 

They said these tides provide a glimpse of what will become routine with continued climate change and sea level rise.

"The problem is that we are going to see more and more of this as sea level keeps getting higher and higher, more of these tides poke through and reach the threshold level," Mark Merrifield with the University of Hawaii Sea Grant Program said. 

Concerns over King Tides include the threat of coastal flooding and erosion.

Beach front hotels not taking any chances, building sand walls and placing sandbags along the shore, hoping to stop the ocean from getting in.

"We are paying close attention to this. We are developing plans in partnership with the State and DLNR to address the beach management issues in Waikiki more comprehensively and more proactively and looking at ways to mitigate these problems in the future," Dolan Eversole with the UH Sea Grant Program said.

Thursday's King Tide may have looked impressive. But an incoming south swell is expected to bring 6 to 10 foot waves over the next two days.

The swell combined with the King Tide could leave damaging impacts.

"We expect that stacking to allow waves to run up much further inland than normal," Eversole said.

May's King Tides are not the last, the tide will rule again in June and July.
