SSW Continues to Fill in, Trade Swell Today
A Small Craft Advisory is posted for all Big Island coastal waters and the ʻAlenuihāhā channel through 6 p.m. Wednesday for east winds up to 25 knots and seas up to 11 feet.
**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 are expected head high today with the best breaks getting up to overhead from time to time on the sets.
Kona side: Wave heights knee/waist/chest high are expected today.
South: Breaks open to the south-southwest swell could get up to knee/waist/chest high. The best spots open to the trade swell could reach chest/head high or slightly bigger on the sets.
A new south-southwest builds in further Wednesday into Thursday and holds through Friday. A slightly bigger swell is expected for the weekend.
We could see a northwest swell for the weekend if a system tracking toward the Aleutians progresses as models are currently indicating. Will keep an eye on it.
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.
