Surf along south facing shores will remain small through the weekend and early next week. Mainly small background energy is expected over the next several days.

A more notable, out of season, northwest swell is expected to arrive Sunday. This swell is associated with a broad low pressure system currently centered over the Aleutian islands just east of the Date Line. A decent sized area of gales were focused within the 300 to 330 deg directional band relative to the islands. A large batch of winds just below gale-force criteria were still focused toward the local area south of the Aleutians, which should make for more of a long-lived event locally. We should expect to see rising surf along north and west facing shores Sunday and Sunday night, that should hold through Tuesday before gradually dropping through midweek. Surf should remain just below advisory levels through the peak of this event late Sunday through early Monday. However, if buoys end up coming in slightly larger than predicted, as we have seen often through the course of the winter, surf heights will near advisory levels by Sunday night.

Surf along east facing shores will hold through the weekend as fresh to strong trades locally and upstream continue south of 1034 mb high centered over the eastern Pacific.

Weather Outlook for Saturday

A strong surface high far northeast of the islands will move southeast and weaken through early next week. A ridge aloft will remain over the area through tomorrow. Early next week, a low aloft will dig toward the area from the northwest and a surface trough will develop west of Kauai. The low aloft, and the surface trough, will weaken by mid- week. A strong new high will build north of the islands during the second half of the week.

Surface observations show partly cloudy skies over the islands. Radars show scattered showers over windward areas and isolated light showers over leeward areas. Some clouds and showers have persisted over the Kona district of the Big Island of Hawaii overnight. Moderate trade winds are blowing over most areas. The clouds over Kona will dissipate over the next few hours. Clouds and showers over windward areas will gradually decrease after sunrise.

A 1033 mb surface high is centered about 1650 miles northeast of Honolulu. Water vapor imagery shows a ridge aloft over the islands. The surface high will keep moderate trade winds blowing through the weekend. The ridge aloft will keep the atmosphere stable. Rainfall will be light and focused over mainly windward areas.

The global models are in excellent agreement through the coming week. A trough aloft will dig toward the islands from the northwest over the weekend, and a low aloft will form about 800 miles northwest of Kauai late Sunday night. Meanwhile, the surface high northeast of the area will move southeast and weaken. Winds over the islands will weaken and veer out of the southeast and the atmosphere will become more moist and unstable. The southeast flow will carry haze from Kilauea over the smaller islands.The southeast flow will be partly blocked by the Big Island, so winds will become variable over the smaller islands, allowing nighttime land breezes and daytime sea breezes to prevail Sunday night through Monday night. The sea breezes will produce afternoon clouds and showers. The land breezes will bring partial clearing overnight.

By midweek the low aloft northwest of the islands will weaken and the atmosphere over the islands will become less unstable. A trough aloft will persist northwest of the area though, so some instability will remain. A strong new high will build north of the area over the second half of the week and bring a return of breezy trade winds. There is likely to be enough moisture and instability to keep windward quite showery after the trade winds return.
