WAIKIKI (HawaiiNewsNow) - Another record-setting round of king tides are rolling into Oahu's shorelines on Friday and Saturday.
"We've been here since last Friday and it keeps coming up every day," said Josef Babbitt, who's visiting from Washington state.
In Waikiki, the city prepped for the higher tides with sandbags and barricades.
Beachgoers prepared, too, creating makeshift walls around their beach blankets with sand and Boogie boards.
On Friday afternoon, the tides were swallowing up whole sections of Waikiki Beach and washing onto the sidewalk in some places.
University of Hawaii researchers said the latest king tide episode is expected to be a record breaker, smashing previous records set in May and June.
The high surf was expected to peak around 3:08 p.m. Friday.
During king tide episodes, coastlines may see flooding as the water level rises well above forecasted highs.
Although the surf is not expected to reach comparable highs again until November, experts warn the king tides could provide a glimpse of Hawaii's future.
As with previous king tide events, UH Sea Grant College officials are calling on residents again to help document the sea level rise.
Matthew Gonser, extension faculty for the Sea Grant College Program, citizen scientist data collected from the past few months of king tides are being used to plan for local and statewide sea level rise in the future.
"What we're actually doing is engaging folks and really empowering them to become citizen scientists," Gosner said, "and collecting data and information that helps us better understand what these hazards - the impacts that can be generated from these hazards."
According to Gonser, about 170 people sent in more than 1,700 photos of the king tides' effects in May and June.
Gosner cautioned residents to remain observant and aware of their surroundings in coastal areas, especially when king tides reach their peak.
"Again, just always being safe and always being aware," Gosner said, "and remembering that the ocean is a fun place but can be a powerful place."
