Synopsis

High pressure drives breezy trades into next week. Expect showers focused windward and mauka during this time. An uptick in shower coverage is anticipated Thursday night into the weekend, particularly overnight and during the morning.

Aviation

Moderate to breezy trades will continue for the next several days. Low clouds and scattered showers will move over windward and mountain areas, with some spillover into leeward sites. VFR conditions are broadly expected, with localized MVFR mainly for windward/mauka sites.

AIRMET Tango remains in effect for moderate low level turbulence over and downwind of terrain for all islands. This AIRMET will likely continue through the next several days.

Marine

Issued at 315 AM HST Mon Jul 6 2026 A strong high pressure ridge centered north of the state will help to drive fresh to strong trades across the local waters through Tuesday, then ease slightly to fresh to locally strong for midweek and beyond. The Small Craft Advisory, currently in effect for all local waters, has been extended through Tuesday afternoon.

A moderate, long period, south southwest (190-200 degree) swell will continue to help boost surf along south facing shores to above seasonal averages today, but just shy of Advisory levels. This swell should gradually lose energy from Tuesday through the remainder of the week. Expect small surf for south facing shores leading into this weekend with mainly background energy.

Surf along east facing shores will remain choppy through the week as fresh to locally strong trades hold. Expect flat to tiny surf along north facing shores through the forecast period.

Watches, Warnings, Advisories

Small Craft Advisory until 6 PM HST Tuesday for all Hawaiian nearshore waters.
