High pressure located far north of the waters will remain nearly stationary through the forecast period maintaining moderate to locally strong trade winds. A Small Craft Advisory (SCA) has been extended for the windier waters and channels around Maui County and the Big Island through Saturday night. SCA conditions look to persist through the beginning of next week.
Surf along south facing shores have peaked through the day just just below advisory levels today as the moderate medium to long period south swell will likely slowly start to decline through the night. Another south swell similar in size is expected during the middle of next week bringing surf back up to near High Surf Advisory level conditions.
Surf along east facing shores will remain choppy in response to the locally strong trade winds over and upstream of the islands. A small medium period east swell from Tropical Storm Iselle has filled in and will hold through Saturday. Another round of east to southeast swells are possible late next week but remains at high uncertainty due to the potential track and intensity of Tropical Storms in the east Pacific.
Small Craft Advisory until 6 PM HST Saturday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Maalaea Bay-Pailolo Channel.
