Detailed Forecast

Synopsis

Breezy trades will gradually weaken through the weekend as a low pressure system developing to the far north weakens the surface ridge over the islands. Clouds and showers will favor windward and mauka areas the rest of today, and to a lesser extent Saturday, before the focus shifts to sea breezes Sunday. Early next week, increasing moisture will move up the island chain from the southeast, increasing rain chances for the state Monday through Wednesday. Moderate to locally breezy trades are expected to return late Wednesday and stay with us through next weekend.

Update

Latest forecast remains on track, therefore no major amendments were needed for this evening's update. Only opted to include haze to the weather grids to account for some vog associated with Kilauea through the next several hours. This will be reevaluated with the morning forecast.

Prev discussion

Issued at 354 PM HST Fri May 29 2026 Radar and satellite show isolated showers mainly windward and mauka this afternoon with mostly sunny skies elsewhere. Trade winds continue, averaging 10 to 15 mph with gusts 15 to 25 mph.
A surface high pressure centered north of the islands will weaken through Sunday and remain fairly weak into Monday. Trade winds will hold through tomorrow, then weaken significantly Sunday. this will allow sea-breezes to develop Sunday, bringing an above-normal amount of cloud cover and showers to leeward areas. Windward areas will still see their typical amount of summer showers.
An enhanced area of moisture will move northwest over the state Monday through Wednesday. This should bring additional showers as the surface ridge to the north strengthens. Trade winds will return Wednesday as the moisture is pushed west of the area.
The remainder of next week should see a return to typical trade winds with showers and clouds once again mainly over windward and mauka areas.

Aviation

Moderate trades should decrease slightly over the weekend. Low cigs and SHRA along windward and mauka locations. MVFR conds possible in SHRA otherwise VFR prevails.
No AIRMETs in effect.

Marine

Moderate to fresh trade winds will steadily ease into the light to moderate range over the weekend as the surface ridge weakens in response to broad low pressure developing near the Aleutian Islands. This will translate to localized land and sea breezes near the coasts late this weekend through early next week. A return of moderate to fresh easterly trades is likely by midweek as the ridge strengthens.
An active pattern is in store for surf along south-facing shores as we head into June due to a series of recent gale- to storm- force lows passing through our swell window near New Zealand over the past week. Expect surf to continue building overnight into Saturday as a long-period south-southwest swell arrives. Our buoys are already reflecting this rising trend with the peak energy registering in the 17-20 second bands this evening. Surf will hover around the advisory level through the weekend. As the swell gradually begins to ease early next week, long-period forerunners from the next south-southwest swell are expected to arrive. Heights may briefly dip below the advisory level Monday night, but as the next swell fills in, surf will likely return to the advisory level Tuesday through midweek as it peaks. A gradual downward trend is then expected through the second half of next week.
A combination of advisory-level surf this weekend and water levels hovering above predicted levels could lead to some wave runup issues, with water sweeping across areas of beaches that typically remain dry. Water levels will steadily lower each day early next week as the next large south swell arrives.
The current small northwest swell will slowly lower through Saturday before fading on Sunday. A small north swell will likely produce surf near seasonal averages along north-facing shores from late Tuesday into Thursday.
Expect surf along east-facing shores to gradually ease through early next week as trade winds become light. A slight increase is possible Tuesday and Wednesday due to a combination of rebuilding trade winds and a wrapping north swell.
