Light winds and humid conditions will persist today as a weak surface trough lingers near the state. Interior clouds and a few showers will develop during the afternoon hours, followed by partial clearing overnight. Trade winds will gradually return Thursday and Friday, bringing a more typical pattern of mainly windward and mauka showers with a few afternoon showers over leeward areas. A slight increase in shower coverage remains possible this weekend as an upper disturbance approaches the islands, followed by stronger trade winds and more stable conditions early next week.

A light background wind prevails with land breezes expected through this morning, transitioning to sea breezes this afternoon. Expect VFR conditions initially, then periods of MVFR conditions as clouds and shower activity develop later along island interiors. Light winds are expected to persist throughout the day; though, trades are anticipated to return by the latter end of the week.
No AIRMETs are currently in effect, however, AIRMET Sierra may be needed this afternoon to account for clouds and showers associated with sea breezes this afternoon.

A trough north of the smaller islands will move very little today and allow for weak to flow to continue across all local waters. Thus, expect diurnally driven late morning and early afternoon sea breezes to develop along waters near the immediate coasts. Thursday into Friday, a surface ridge building northwest of the state will bring a return of light to locally moderate northeasterly trades. Trades will then strengthen into moderate to locally fresh range by this weekend.
A moderate medium-period northwest swell will gradually fade through the rest of today. A new long period swell originating from a gale force low south of Kamchatka will build tonight and give another boost to north and west shore surf Thursday and Friday, but should remain below advisory levels. Surf will gradually decline over the weekend into early next week.
A small, long-period south swell, generated from a storm-force low that tracked southeast of New Zealand last week, will fill in today and likely provide a small bump in south shore surf through the end of the week.
Surf along east facing shores will remain below normal during the next several days due to the lack of strong trades over and upstream of the islands. Surf along east facing shores will get a small bump up into the weekend as trades gradually increase.
None.
