Breezy trades will focus low clouds and showers across windward and mauka areas through the middle of next week. A plume of moisture moving south of the islands will increase rain chances over the eastern end of the state through Monday, followed by drier conditions through mid-week. Brewing disturbances within the tropics will need to be monitored for more organized development the next several days.
Moderate to fresh trades expected for the next several days. Low cigs and SHRA should mainly impact windward and mauka spots. Isol IFR and some MVFR conds likely in heavier SHRA, otherwise VFR prevails.
AIRMET Sierra is in effect for mtn obsc for windward locations of all islands.
AIRMET Tango is in effect for mod turb downwind of island terrain. This AIRMET will likely be needed for next several days.
Issued at 351 PM HST Sat Aug 8 2026 Fresh to locally strong trade winds will persist through at least Wednesday as high pressure remains anchored northeast of the state. A Small Craft Advisory remains in effect for the typical windy channels and waters around Maui County and the Big Island through Sunday afternoon. This advisory many need to be extended further, as borderline conditions will prevail through at least Wednesday. Later in the week, the focus will shift to the deep tropics southeast of the state. A tropical cyclone could develop and have an effect on local winds, seas and weather as early as Friday.
Continued small overlapping south-southwest swells will produce south shore surf near August average this weekend and near to above average Monday and Tuesday. A larger swell will arrive Tuesday night and may push surf to the High Surf Advisory level late Wednesday through Friday. This swell should slowly decrease next weekend.
Along east-facing shores, short-period trade wind swell will generate surf just below August average through Thursday. Depending on how potential tropical cyclone development plays out southeast of the islands, an increase in southeast swell is possible Friday and next weekend. Aside from wrapping trade wind energy, surf along north-facing shores will remain flat to tiny through the week.
Due to a combination of peak monthly high tides and water levels running higher than predicted in a few locations, minor coastal flooding will be possible around the afternoon high tide as early as Sunday, with peak conditions Monday through Wednesday.
Small Craft Advisory until 6 PM HST Sunday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Maalaea Bay-Pailolo Channel.
