A Small Craft Advisory is posted for the ʻAlenuihāhā channel as well as waters to the south and west of the Big Island through 6 a.m. Friday.
**Click directly on the images below to make them larger. Charts include: Big Island projected winds, tides, swell direction & period and expected wave heights.**
Hilo side: Wave heights for spots exposed to the trade swell are expected to be waist/chest/head high today.
Kona side: Wave heights are expected to be ankle/knee high today, some spots could be flat.
South: Wave heights are expected to be ankle/knee high high today, some spots could be flat. Spots catching trade swell could get up to waist/chest/head high.
Tropical system Ivette is not looking to send significant swell to the islands. Small swell will mix in Tuesday through Thursday. Omais (near Japan), Javier (near Mexico) and Conson (east of Mariana Islands) aren’t looking like wave makers for us.
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.
