By Meteorologist Malika Dudley / Email: [email protected]
A Small Craft Advisory is in effect for the Pailolo and ʻAlenuihāhā channels as well as Māʻalaea Bay through 6:00 a.m. Sunday. East winds up to 25 knots are expected with rough seas up to 11 feet.

North: Wave heights of about waist/head high are expected today. Easterly breaks (Hana) will be best exposed and may be slightly overhead on the sets.
West: Wave heights knee/waist high are expected. Many spots will be blocked by other islands.
South: Wave heights knee/waist high are expected.
Small pulses out of the south are expected but nothing super notable. A better angled swell expected the second half of next week with waves possibly up to waist high or more. Otherwise, the SPAC is looking pretty quiet.
Trade swell will push into northeasterly exposures over the next few days. Hurricane Guillermo is located far east southeast of the state moving toward the west northwest. Although the track and intensity of the storm remains uncertain so far in the future, adverse effects for Hawaiian coastal waters next week can not be ruled out. Building east-southeast swell is expected to move in as early as Monday, peaking Wednesday.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
