Watches & Warnings

Special Statement
Issued: 4:51 AM HST May. 25, 2017 – National Weather Service

... Coastal flooding anticipated in conjunction with high tides
and incoming South Shore surf...

Coastal flooding impacts associated with record level King tides
will continue each day through the Memorial Day weekend. Flooded
beaches, vulnerable low-lying roads and coastal areas, boat ramps
and docks will be impacted during these hours surrounding the late
afternoon and early evening high tides each day.

The peak tides are expected Friday and Saturday, which will
coincide with a new south swell that will generate advisory-
level surf along along south facing shores late Friday through
Saturday. A combination of large surf and high water levels will
result in additional wave run up, likely flooding beaches along
the south shores that typically remain exposed during normal
conditions. Surf and water levels are forecast to gradually trend
back toward normal through the upcoming week.

The following are the daily forecast tide levels and times for
Honolulu which will correspond to coastal flooding impacts.

5/25 Thursday 4:21 PM HST 2.4 feet
5/26 Friday 5:07 PM HST 2.5 feet (south shore surf expected)
5/27 Saturday 5:55 PM HST 2.4 feet (south shore surf expected)
5/28 Sunday 6:46 PM HST 2.3 feet
5/29 Monday 7:40 PM HST 2.1 feet

Other islands and shorelines can expect similar daily high tide
times. Please visit the website tidesandcurrents.NOAA.Gov for
