Oahu and Kauai have been experiencing a corridor of enhanced showers this morning, but don't expect them to stick around for long. According to the National Weather Service - Honolulu, surface troughing responsible for the wetter conditions is expected to move westward and away from impacting the islands throughout the day. An upper low southwest of the islands isn't posing a significant threat either; it's merely responsible for the high clouds drifting across the skies.
Weekend forecast looks to be a mixed bag of moderate trade winds and the occasional showers, particularly in windward and mauka areas. A brief uptick in the trade winds is on the horizon for next week, reported by National Weather Service - Honolulu, before they die down again as another round of troughing inhibits the subtropical ridge's strength.
In terms of air travel, moderate trades should make for mostly smooth skies. Pilots and passengers can expect "brief MVFR conditions in scattered showers," particularly during the night and early morning hours, yet "VFR conditions should prevail across the island chain," as stated by National Weather Service - Honolulu. As for those on the sea, mariners can anticipate gentle trades through tomorrow with the possibility of stronger trades early next week, which could prompt Small Craft Advisories starting Tuesday.
Surf's up—or, at the very least, consistent for the next few days. Nearshore buoys have clocked in with a small, long period south swell this morning, which should keep south-facing shores at around waist-high surf. The north shores aren't left out of the action either; a "small short to medium period north swell (350-360 degree)" is predicted to roll in by the morning, potentially leading up to advisory-level surf early next week, as mentioned on the NWS. And for the west-facing shores, they'll continue to experience combined north and south swell wraps, leading to elevated surf conditions.
