FZHW52 PHFO 221343 SRFHFO Surf Zone Forecast National Weather Service Honolulu HI 343 AM HST Thu Feb 22 2018 Oahu- 343 AM HST Thu Feb 22 2018 Surf along north facing shores will be 8 to 10 feet today, lowering to 5 to 8 feet Friday. Surf along west facing shores will be 5 to 8 feet today, lowering to 4 to 6 feet Friday. Surf along east facing shores will be 4 to 6 feet today, increasing to 6 to 8 feet Friday. Surf along south facing shores will be 3 feet or less through Friday Outlook through Thursday March 01: The current west-northwest swell will slowly subside into the weekend. No other significant northwest swells are expected through the period. An elevated trade wind swell is expected to bump surf up to advisory levels along east facing shores by late Thursday or Friday. Surf will continue to build through the beginning of next week, and may reach warning levels by midweek. A small long-period south swell could produce a small bump in surf this weekend for south facing shores. Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.

Oahu Surf Climatology

Surf heights will vary between different beaches and at the same beach at different break areas.

DISCUSSION: SUMMARY:. Mid week peak from WNW with steady easterly windswell.

DETAILED:. Mid Tuesday on northern shores has declining breakers from 315-330 degrees at levels below the active season, Sep-May, average. An increase is predicted for Wednesday.

A jet stream block near the central to eastern Aleutians has kept mid latitude wave sources west of the Date Line. This is making for mostly below average surf.

A low pressure gained storm-force east of Japan 2/18 with seas growing above 30 feet beyond 2000 nm away over the 300-310 degree band. The low was forced northward by the blocking ridge once near 170E.

Long-period surf from this source should fill in locally overnight into Wednesday from 300-310 degrees. It should peak late Wednesday near the seasonal average. It should drop below average from 300-315 degrees Thursday as a new event fills in late in the day from the same direction.

A second low was right behind the 2/18 system east of Japan. The follow-up low was more compact and weaker. It hit the sharp corner from east to north in track near the same area around 170E on 2/19. Though smaller and weaker, it was acting upon existing seas from the first system.

This event should build late Thursday, peak Friday at levels below average from 300-310 degrees, and drop to small levels over the weekend from 300-320 degrees.

Mid Tuesday on eastern shores has breakers from 40-75 degrees at levels above the trade windswell average. A slight drop is predicted for Wednesday.

A large area of surface high pressure fills the NE Pacific between Hawaii and the USA west coast. A fetch of fresh to strong trades extends from just east of Hawaii eastward to near 130W, nearly 1500 nm. This has allowed the dominant wave period to lean on the swell side of windswell. Longer wave periods allow greater size to breakers for the given wave heights.

See the latest NWS State Forecast Discussion regarding the local winds and skies. Oahu is modelled to be near a pivot point with stronger winds to the east and lighter winds to the west. Stay tuned to the freshest forecasts.

Wave-wise, the long fetch of fresh to strong upstream breezes ensures a long-lived, above average windswell regardless of the local winds. Heights are expected to remain above average through the period with a maximum within Friday to Sunday from 60-100 degrees.

Mid Tuesday on southern shores has inconsistent, tiny to small breakers for select high refraction zones. Similar surf is likely for Wednesday.

The easterly windswell should keep surf for select exposures through the period with better odds Friday to Sunday as the dominant windswell direction becomes more straight easterly.

A storm-force low pressure tracked east along 60S SE of Tasmania 2/15-17. A low, long-period event is possible locally building late Friday, peaking late Saturday, and dropping Sunday from 208-220 degrees.

Into the long range, hints of gales SE of New Zealand within 2/23-27 that could make for small SSW events locally within the first week of March.

In the northern hemisphere, the blocking ridge near the Aleutians should keep surf below average most days. Well below average surf is suggested for 2/26-28.

Above average easterly windswell should continue 2/26-28.

Long range forecasts are subject to major revisions.

This collaborative forecast will resume on Friday, February 23.
