Breezy trades will focus clouds and showers over windward and mauka areas through the week, especially during the overnight and early morning hours.
Typical June weather will persist through the week, with locally breezy trade winds focusing showers over windward and mauka areas. Broad surface high pressure far north of the state will maintain trades near current strength through at least Wednesday, followed by a slight decrease in winds on Thursday as the high shifts to the northeast. A mid-level ridge overhead will maintain stable conditions, and little organized moisture is forecast to be moving along the trade wind flow. As a result, expect showers to be focused along windward areas, especially at night, with rainfall accumulations of less than a half of an inch per day at most sites. Leeward areas will continue to be rather dry, except for scattered afternoon showers along the Kona slopes of the Big Island. Thin high clouds will pass over the islands into Monday, then dissipate as an upper-level low west of the state drifts away.
Stable, breezy trades deliver clouds and showers mainly to windward and mauka zones through the period. VFR prevails, but MVFR will be possible within any showers.
AIRMET Tango remains in effect for low-level lee turb.
High pressure north of Hawaii will drive trade winds through the week, with a slight weakening trend as the high moves away eastward. A Small Craft Advisory (SCA) for the windier waters and channels near Maui and the Big Island goes through Monday night, likely extending beyond this point.
A series of small, long-period, south swells will help boost surf heights along south facing shores though the week. The current south swell will decline over the next couple days followed by another south swell from Wednesday into Thursday.
Rough and choppy surf along east facing shores will continue this week. Surf will remain nearly flat along north facing shores throughout the forecast period.
Small Craft Advisory until 6 AM HST Tuesday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.
