FZHW52 PHFO 190149 SRFHFO Surf Zone Forecast National Weather Service Honolulu HI 349 PM HST Fri Aug 18 2017 Oahu- 349 PM HST Fri Aug 18 2017 Surf along south facing shores will be 3 to 5 feet through Saturday. Surf along east facing shores will be 2 to 4 feet through Saturday. Surf along north facing shores will be 2 feet or less through Saturday. Surf along west facing shores will be 1 to 3 feet through Saturday. Outlook through Friday August 25: A small south southeast swell will subside through the weekend. Surf along east facing shores will rise during the second half of next week due to strengthening trade winds. 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.

DISCUSSION:

SUMMARY:.

Low summer conditions.



DETAILED:.

Mid Friday on eastern shores has declining breakers from 50-90

degrees at levels below the trade windswell average. Minimal trade

windswell surf is predicted for the weekend.



See the latest NWS State Forecast Discussion for an explanation of

the weather features driving the local trend in trades.



The upstream trade wind region E to NE of Hawaii has moderate or

less speeds 8/17-18. It is expected to remain about the same into

Monday. This should keep breakers well below average.



Uncertainty remains 8/18 on the forecast of the tropical

disturbance to the SE of the Big Island. See the latest comments

from the Central Pacific Hurricane Center. Stay tuned for update

in case there is a change relative to the table above for the

local winds and waves within 8/20-23.



Mid Friday on northern shores has near flat conditions. Similar

surf is predicted for Saturday.



A weak low pressure near the Dateline just south of the Aleutians

8/18 has fresh breezes aimed at Hawaii beyond 1600 nm away. This

magnitude is too low and the distance too great to expected surf

beyond tiny locally from this source.



Mid Friday on southern shores has inconsistent breakers to the

summer average level from 155-175 degrees. Heights should slowly

drop Saturday.



The surf was generated by an austral mid latitude low pressure

system SSE of French Polynesia 8/10-12. The swell trains received

partial shadowing by Tuamotu archipelago east of Tahiti on their

travel towards Hawaii.



The NOAA southern Hawaii buoys 51004 and 51002 show the swell

energy in the 15-16 second band has peaked and is declining 8/18.

The swell should have another day of energy in the 12-14 second

band on Saturday then slowly fade to background Sunday from the

same direction.



Strong trades near French Polynesia 8/14-18 should be the dominant

summer background surf for 8/21-23 from 140-170 degrees. Other

than the shadow factor from Tuamotus...the size and strength of

the trades suggests this windswell could be a notch higher than

typical austral trade windswell in Hawaii.



Into the long range...the strong trades shifted eastward 8/17-18

as a subtropical low pressure deepened near 125W. This area is

less shadowed by the Tuamotus. This should give a bit better odds

for the austral trade windswell over the weekend of 8/26 from

130-160 degrees. A severe gale in the Tasman Sea formed 8/17 and

is expected to remain active through 8/19. This could add surf to

near the summer average over the weekend of 8/26 from 208-220

degrees.



Tropical Depression 13-E has formed 8/18 SW of Baja. It will be

monitored for surf potential locally. Wave models are suggesting

remotely-generated swell arriving in Hawaii from 90 degrees

within 8/23-25. Size is likely to be below the trade windswell

average.



This collaborative forecast will resume on Tuesday...August 22.
