Detailed Forecast
Synopsis
Trade winds will continue through the weekend and into next week, bringing showers to the usual areas, with Sunday seeing the most showers. A trough may move close enough to put us in a wetter pattern from the middle to the end of next week, but confidence is not high at this time.
Short term update
Issued at 915 PM HST Thu Feb 12 2026
No changes to the forecast philosophy at this time, and with the forecast on track, no updates anticipated this evening.
Prev discussion
Issued at 307 PM HST Thu Feb 12 2026
Scattered showers were occurring this afternoon across all islands, favoring windward and mauka areas, but also in the Kona region of Big Island. Precipitation recorded so far today is generally around a tenth of an inch or so, with higher amounts at higher elevations and in some windward locations. Skies were partly to mostly cloudy, and highly variable in both time and space. Trade winds were blowing out of the east averaging 10-20 mph with gusts 20-30 mph.
A strong surface high north of the state, associated with a high- amplitude upper level ridge, will get even stronger through Saturday before weakening Sunday into early next week. The result for our weather will be a continuation of trade winds and the typical windward and mauka showers that come with that. Winds will be moderate, but below advisory threshold over land.
An enhanced band of moisture will move east to west through the state Sunday into Sunday night, bringing a slight increase in showers. The upper level ridge referenced earlier will shift east and weaken Monday into Tuesday as a high-amplitude trough attempts to move east across the central Pacific. By Wednesday and Thursday of next week, models show a large spread of potential strength and location of this next upper trough. The latest deterministic GFS shows a moderate closed low moving into position just a few hundred miles northwest of the state. This would like put us back in a wet pattern for the middle to latter part of next week. The latest EC has most of the energy going farther north of the state, with only weak troughing to our west. The ensembles are split as well, so we will continue to watch this potential system over the coming days until some convergence in solutions occurs.
Aviation
Issued at 307 PM HST Thu Feb 12 2026
Breezy trades will continue to persist over most of the island chain. Intermittent mountain and windward showers are expected to persist as well, with MVFR conditions possible under shower activity. Leeward sites expected to remain VFR.
AIRMET Sierra is in effect for mountain obscuration for Kauai, Oahu, Molokai, Maui, and the Big Island for windward sections due to ongoing showers and low ceilings. Conditions are largely expected to persist through the evening.
AIRMET Tango remains in effect for moderate turbulence below 7 kft for leeward sides of the islands. Conditions are expected to persist for the next several days.
Marine
Issued at 915 PM HST Thu Feb 12 2026
Strong high pressure building far north of the waters will continue to drift east supporting moderate to strong easterly trade winds and elevated seas into next week. Winds look to maintain strong speeds but veer slightly early next week as high pressure continues to tracks east and a potential disturbance may develop to the west northwest of the islands too. A Small Craft Advisory (SCA) is in effect for all coastal waters through Friday night and will likely be extended through the weekend.
A small to moderate medium to long period northwest swell will continue to build slowly overnight and peak Friday into Saturday just below High Surf Advisory (HSA) levels, before declining through the weekend. Looking into next week, small background northwest swell energy is expected through the forecast period.
Surf along east facing shores will continue to build over all waters into this weekend and early next week due to persistent strong trades locally and upstream of the islands. A HSA is likely for east facing shores over the weekend.
Surf along south shores remains small with some background trade wind swell for select exposures.
