Swell Summary
Surf along the north and west facing shores will build today as this medium sized long period northwest (320 degree) swell spreads southeastward across the islands, peaking on Tuesday, then gradually lowering Wednesday through Friday. Expect a large increase to north and west shore surf heights through Wednesday, approaching High Surf Advisory (HSA) levels as the swell energy peaks on Tuesday.
Small surf along the south facing shores will slowly increase this week as two small long period south-southwest (200-210 degree) and south (180-190 degree) swells build into the region. This southern source swell energy will peak on Wednesday and Thursday near HSA levels. Surf heights along south facing shores will then gradually lower from Friday into next weekend.
Small surf along east facing shores will trend up through the week as trades strengthen east of the islands. East shore surf will return to seasonal levels Thursday through the weekend.
