FZHW52 PHFO 161408 SRFHFO Surf Zone Forecast National Weather Service Honolulu HI 408 AM HST Thu Aug 16 2018 Oahu- 408 AM HST Thu Aug 16 2018 Surf along south facing shores will be 1 to 3 feet today, building to 2 to 4 feet Friday. Surf along east facing shores will be 1 to 3 feet through Friday. Surf along west facing shores will be 2 feet or less through Friday. Surf along north facing shores will be 1 to 3 feet today, lowering to 2 feet or less Friday. Outlook through Thursday August 23: Overall, small surf is expected along all shores through the weekend. A small south-southeast swell is expected to fill in today, peak tomorrow and hold through Saturday at heights below the summer average. Models are suggesting a broad area of low pressure developing near the Aleutian Islands this weekend. This may bring a small to moderate north to north-northwest swell starting around Monday night or Tuesday of next week. We will continue to monitor the development of tropical cyclone Lane for any surf potential. 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:. Low pattern.

DETAILED:. Mid Wednesday on northern shores has tiny breakers from 315-340 degrees. Similar heights are predicted for Thursday.

Angular spreading of windswell out of a fetch of strong breezes near the Date Line 8/12 is giving the low surf for 8/15. The NOAA NW Hawaii buoys 51001 and 51101 are not available for guidance. Wave Watch III keeps the swell into Thursday.

Models show a large area of low pressure forming within 40-55N, 155-175W 8/17-18. The closer portions of strong breezes could begin tiny to small breakers out of 330-350 degrees on Monday 8/20.

Mid Wednesday on eastern shores has low breakers from 70-90 degrees. Similar surf is predicted for Thursday.

Weak windswell from tropical systems John and Kristy 8/13-15 locally were lower than modelled by the Wave Watch III. PacIOOS/CDIP buoys for easterly exposures from Kaneohe to Hilo show a drop in the 8-12 second energy 8/12-13. It is fading to nil 8/13.

Upstream fresh trades and locally increasing trades over the weekend into Monday 8/18-20 should trend breakers from windswell up during this time from 70-90 degrees.

Mid Wednesday on southern shores has background surf mostly from trade windswell out of the southern hemisphere. Surf should remain near background levels on Thursday.

A compact gale near 35S, 155W tracked slowly SSE 8/9-11. The fetch toward Hawaii was short and narrow. Low, moderate-period swell of 13-15 seconds is modelled to slowly build locally Thursday 8/16 from 175-185 degrees. This event should be filled in by Friday and hold into Saturday at levels below the summer average. Surf should return to background levels by Sunday 8/19.

Into the long range, a large ridge to the SE of New Zealand is keeping the primary source region at minimal potential 8/6-15. More activity is seen in the Tasman Sea 8/13-15, but not of caliber to bring surf in Hawaii beyond background locally 8/21-23.

Models show a compact gale south of the Aleutians due north of Hawaii 8/18 moving slowly, then weakening 8/19. It could bring in small NNW surf 8/21-23.

Tropical system Lane in the eastern tropical Pacific will be monitored for surf potential. See the latest statements and forecasts from the National Hurricane Center.

Long range forecasts are subject to low confidence.

This collaborative forecast will resume on Friday, August 17.
