Detailed Forecast

Synopsis

Breezy to windy trade winds are expected this week. Winds will be strongest in higher terrain areas, passes, and areas immediately south through west of mountains across all islands. Showers carried in on the trade will be focused over windward and mauka areas. Moisture may increase this coming weekend.

Discussion

Issued at 335 AM HST Mon Feb 16 2026
Trade winds continue this morning, and scattered showers remain focused on windward and mauka areas. Gusts 40 to 50 mph have occurred on each island from Oahu southeast to the Big Island. Skies were mostly cloudy. Some clearing is expected in leeward areas this afternoon, but windward areas will remain mostly cloudy.
Latest guidance shows that trades will remain easterly instead of veering to ESE as was shown a few days ago. Wind speeds have remained elevated overnight, and the decision was made to put a Wind Advisory back out through tomorrow afternoon over the areas that typically get the windiest during strong easterly trades. Wind speeds are forecast to remain relatively high for most of the coming week. No significant moisture surges are forecast for the next few days, so we expect a typical pattern of windward showers. These will be more numerous at night, but still present during the days. A few may carry over to leeward areas at times. There is some model agreement on enhanced moisture from late Friday through this coming weekend, but at this time range confidence is not high.

Aviation

Issued at 335 AM HST Mon Feb 16 2026
Breezy easterly trade winds will persist during the next couple of days. Showers will favor windward and mauka areas, bringing some brief MVFR cigs/vsbys at times. VFR conditions should generally prevail in leeward locales.
AIRMET Sierra remains in place for mountain obscuration over windward sections of Kauai and the Big Island. Conditions should improve here later this morning.
AIRMET Tango remains in effect for moderate low level turbulence over and downwind of the terrain of all islands. This AIRMET will likely persist through at least Tuesday.
Kilauea Episode 42 has ended. A volcanic ash SIGMET, under series Papa, remains in effect through 1635Z to account for some lingering ash aloft. This SIGMET will likely be cancelled later this morning unless volcanic activity resumes.

Marine

Issued at 335 AM HST Mon Feb 16 2026
A strong high pressure system far north of the Hawaiian Islands will continue to drift farther south through Wednesday. This closer proximity to the islands will keep strong and gusty trade winds in the regional forecast through at least Wednesday. A slight decrease in trade wind speeds may develop from Thursday into Friday as the high weakens briefly.
Surf heights along east facing shorelines will remain solidly within the High Surf Advisory (HSA) range through Wednesday. The HSA was extended until Tuesday evening for now, and may need to be extended into Wednesday at a later date.
Small surf heights remain in the forecast for north, west and south facing shores lasting into Saturday, due to an absence of significant swell energy in the medium range forecast.
In the extended range forecast, the forerunners of the next moderate to large, long period north (010-020 degree) swell appears to arrive by late Sunday night, building swiftly to advisory levels through next week Monday, and then slowly declining into the middle of next week.
