Surf along south facing shores remains elevated Saturday morning due to a large south-southwest swell. Surf heights are expected to peak later today, then gradually diminish into early next week. As a result, a High Surf Advisory remains in effect through Sunday afternoon for all south facing shores.

In addition to the elevated surf along south facing shores, coastal flooding impacts associated with record-level King Tides will continue each day this weekend along all shores, especially in Maui County and Oahu. Beaches and shorelines, boat ramps and docks, and vulnerable low-lying roads and structures will be impacted during these late afternoon and early evening high tides.

Elsewhere, surf along east facing shores will trend down through the weekend due to the light winds. However, a small short-period north-northeast swell will support small surf along east facing beaches and reefs with exposure to swell energy from this direction through Monday.

Small background surf is expected to persist along north facing, mainly at locations exposed to the north-northeast swell mentioned above. The latest wave model guidance continues to show a small to moderate north-northwest (330-340 deg) swell filling in from Monday night through mid-week due to the fetch associated with the circulation around a surface low tracking north of the state later this weekend.

Weather Outlook for Saturday

Light easterly winds with localized land and sea breezes will prevail across the island chain through the rest of Memorial Day weekend as pressure gradient slackens across the region. Passing showers will favor windward areas, while convection developing in the afternoons and evenings over the islands will bring showers to the interior and leeward sections. Unsettled weather is possible through Sunday as an upper level trough passes over the state. Typical trade wind weather is expected to return early part of next week as high pressure is expected to strengthen north to northeast of the islands.

Light easterly winds continue across the islands early this morning with widespread land breezes as pressure gradient remains relax across the region. A little more low clouds have developed in the island vicinity overnight, with persistent clouds over the Big Island as well as windward east Maui. Early morning Lihue and Hilo soundings continue to reveal a somewhat dry airmass in the island vicinity, with Lihue sounding still depicting a more unstable airmass over the western portion of state.

A weak pressure pattern will continue in the island vicinity through the rest of the Memorial Day weekend as high pressure far northwest continues to weaken and edge south, resulting in light synoptic easterly flow across the area. Widespread daytime sea breezes and overnight land breezes will prevail. Clouds will build over the interior and leeward areas of the islands during the day under the converging sea breezes, with showers developing, while there will be some clearing at night under the diverging land breezes. The background light easterly wind flow may also bring some clouds and showers to the windward areas at times. An upper level trough currently northwest of the islands will pass over the area through Sunday. It will bring cold temperatures aloft, leading to the airmass in the island vicinity to become more unstable. Showers will be enhanced, with locally heavy downpours possible, especially in the afternoon and evening for the next couple of days. As the upper level trough moves closer to the state later today, Kauai and Oahu may see more active weather. The focus of unsettled weather is expected to shift to the eastern portion of the island chain Sunday as the upper level feature advances east. Atmospheric conditions may become unstable enough for thunderstorms to develop over the Big Island. Therefore, have introduced a slight chance of thunderstorms to leeward Big Island Sunday afternoon and evening in this forecast package. Furthermore, temperature at the Big Island summits may become cold enough for a chance of freezing rain to affect that area.

High pressure far northeast of the state is expected to extend westward early part of next week, and then stay north to north-northeast of the islands toward the later part of next week. This will bring stronger trade winds back to the island chain beginning late Tuesday. Winds are expected to strengthen to moderate levels by the second half of next week. Airmass in the island vicinity is expected to become more stable as an upper level high passes north of the region. Thus, typical trade wind weather is expected for the islands for much of next week, with passing low clouds and showers affecting mainly windward areas.
