Summary

A high north-northwest of the area will keep trade winds in place throughout the week. Trades get breezy over the weekend, then windy next week. Clouds and showers favor areas facing the wind. Remnants of a front can lead to rain showers on Sunday and Monday.

discussion

A strong high far north northwest of the islands will continue to drive trade winds across local waters as it slowly moves southeast until early next week. The satellite loop shows scattered low clouds to clear the sky over the leeward sections of the smaller islands and patchy broken low clouds over the windward areas. Broken to cloudy clouds cover windward and southeastern parts of the Big Island. Radars show sporadic to sporadic showers over the islands, mostly in windward sections.
Trade winds will concentrate the showers over windward areas until the beginning of next week. A frontal cloud band can lead to an increase in wind showers on Sunday and Monday. As the high shifts southeast over the weekend, the trade winds become breezy, with windy conditions for the first half of the next week.

aviation

Moderate to locally strong trade winds will occasionally bring low clouds and showers over the islands in the course of the morning. AIRMET SIERRA is installed on most windward slopes for fast-paced mountain darkening.
AIRMET TANGO is also in effect for moderate turbulence at a low level over the terrain and immediately downwind on all islands due to the breezy winds. AIRMET Tango will probably go on all day.

Fresh to strong northeast trade winds will ease into the moderate to fresh range tonight through Friday. The guide shows the winds turning from the east from this weekend through early next week that will become strong over most Hawaiian waters. High winds combined with large seas with a mix of brief wind waves and a moderate northeast swell late Monday will result in harsh conditions with small craft advisory winds and swell early next week.
Surfing along the north and west coasts will last through Friday and then descend this weekend when the small northwest swell subsides. The guidance shows a decent gradient with fresh north winds lining up over a large area northeast of the region this weekend that will support a small, brief north-northeast swell through Sunday.
Surfing along the south-facing coastlines will continue to decline through Friday as the south swell subsides. Over the weekend, a mix of southern and southeastern swell energy will be enough to keep the surf from flattening, which should last until early next week.
Surfing along the east-facing coastlines will stay small until Saturday and then build up from Sunday to Monday when local trade picks up. Although confidence in the details remains low due to cycle-to-cycle inconsistencies, there is good agreement that a compact storm will form around 1000 nm northeast of the state late Saturday to Sunday, which could create a moderate northeast swell. This swell, which arrives on Monday evening, in combination with strong trades, could lead to a surf at an advisory level for exposed east coasts from Monday night to the middle of the week.
