**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 wrap are expected to be waist / shoulder high at the best breaks. As the day goes on, we could see overhead to double overhead waves on the sets by sunset.
Kona side: Wave heights are expected to be waist / head high today. On the sets the best spots with west-northwestern exposure could see waves in the overhead range.
South: Some spots on the Kona side may get wrap out of the west-northwest up to waist/head high and standout spots will see overhead waves from time to time.
There will also be a series of small, mainly background south swells through the week.
Easterly trade wind swells will remain rather low for the next several days.
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.
