Detailed Forecast

Synopsis

A high north northwest of the area will keep trade wind weather in place through the week. Trades will become breezy over the weekend, then windy next week. Clouds and showers will favor windward areas. Remnants of a front may make showers more widespread Sunday and Monday.

Discussion

A strong high far north northwest of the islands will continue to drive trade winds across local waters as it moves slowly southeast through early next week. Satellite loop shows scattered low clouds to clear skies across leeward sections of the smaller islands and patchy broken low clouds over windward areas. Broken to overcast clouds cover windward and southeast portions of the Big Island. Radars show isolated to scattered showers over the islands, mostly across windward sections.
Trade winds will keep showers focused over windward areas through early next week. A frontal cloud band may bring an increase in windward showers Sunday and Monday. As the high shifts southeast over the weekend, trade winds will become breezy, with windy conditions possible for the first half of next week.

Aviation

Moderate to locally strong trade winds will deliver scattered low clouds and showers across the islands through the morning. AIRMET SIERRA is posted for tempo mountain obscurations along most windward slopes.
AIRMET TANGO is also in effect for moderate low level turbulence over and immediately downwind of the terrain on all islands due to the breezy winds. AIRMET Tango will likely continue through the day.

Marine

Fresh to strong northeast trade winds will ease into the moderate to fresh range tonight through Friday. Guidance depicts the winds shifting out of the east and becoming strong over most Hawaiian waters this weekend through early next week. Strong winds combined with large seas associated with a mix of short-period wind waves and a moderate northeast swell arriving late Monday will translate to rough conditions with Small Craft Advisory winds and seas early next week.
Surf along north and west facing shores will linger into Friday, then lower this weekend as the small northwest swell fades. Guidance depicts a decent gradient with fresh northerly breezes setting up over a large area northeast of the region this weekend, which will support a small, short-period north-northeast swell by Sunday.
Surf along south facing shores will continue to ease through Friday as a south swell lowers. Over the weekend, a mix of background south and southeast swell energy will be enough to keep the surf from going flat, which should hold into early next week.
Surf along east facing shores will remain small through Saturday, then begin to build Sunday into Monday as the local trades become strong. Although confidence in the details remains low due to inconsistencies from cycle-to-cycle, there is decent agreement that a compact gale will form around 1000 nm northeast of the state late Saturday through Sunday that could generate a moderate northeast swell. This swell arriving Monday night combined with strong trades could lead to advisory-level surf for exposed east facing shores Monday night through through midweek.
