FZHW52 PHFO 200202 SRFHFO Surf Zone Forecast National Weather Service Honolulu HI 402 PM HST Tue Jun 19 2018 Oahu- 402 PM HST Tue Jun 19 2018 Surf along south facing shores will be 2 to 3 feet through Wednesday. Surf along west facing shores will be 1 to 2 feet through Wednesday. Surf along east facing shores will be 1 to 3 feet through Wednesday. Surf along north facing shores will be 1 to 3 feet through Wednesday. Outlook through Tuesday June 26: Surf will gradually build Thursday through the weekend along east facing shores as the trades strengthen. Small surf will continue elsewhere with no significant swells anticipated through the weekend. Overlapping long-period south swells will be possible through the first half of next week. 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:. Wave minimum around the compass.

DETAILED:. Mid Monday on northern shores has declining breakers from 270-020 degrees. Small breakers are expected to continue on Tuesday.

A weak low pressure 6/16 near 35N west of the Date Line had fresh to strong breezes over the 295-310 degree band. The system weakened as it moved east. Small, short-period breakers for more westerly exposures are expected to increase Tuesday and drop Wednesday.

No other sources of surf are expected from the mid latitudes of the North Pacific this period.

Mid Monday on eastern shores has declining low surf from 000-090 degrees. Heights should be at an east side minimum on Tuesday.

See the latest NWS State Forecast Discussion regarding the trend this week for local winds and skies.

ASCAT satellite 6/18 shows a large area of gentle or less winds over the trade windswell source region E to NE of Hawaii. Similar winds are expected into mid week. Well lower than normal breakers are on tap into Thursday.

Models show surface high pressure moving east from the Date Line along 40N 6/22 increasing in strength north of Hawaii by 6/23. Local and upstream trades to the E to NE are expected to freshen and trend breakers from windswell to average levels by Saturday out of 60-90 degrees.

Mid Monday on southern shores has declining breakers from 160-190 degrees. Below average conditions are predicted for Tuesday.

Mid latitudes of the southern hemisphere from longitudes of Tasmania to S of French Polynesia 6/12-16 were dominated by surface high pressure. No swell beyond tiny to small is expected locally this period 6/19-23.

Into the long range, the zone SE of New Zealand returned to a cyclonic mode 6/17. A hurricane-force system at the eastern edge of the Hawaii swell window hugging the Antarctic ice sheet 6/17-18 has low odds of giving low, long-period surf locally Monday 6/24 from 170-190 degrees.

Better odds for the following days. Models show gales behind a front pushing north from 60S to 40S just east of the Date Line 6/18-19. This should give an event near the summer average 6/26-27 from 180-195 degrees.

Models show a following mid latitude cyclone to near 950 mb 6/19-20 as the system steers ENE from SE of New Zealand. A large fetch of severe gale to storm- force winds should build seas over 30 feet. This source has potential to bring long-period breakers above the summer average locally 6/27-28 from 170-190 degrees.

Predicted fresh trades with a long fetch E to NE of Hawaii should make for above average breakers from windswell out of 60-90 degrees 6/24-28.

No surf is expected from mid latitudes of the north Pacific.

Long range forecasts are subject to low confidence.

This collaborative forecast will resume on Wednesday, 20 June.
