Hilo side: Wave heights are expected chest/head high today with the best breaks getting up to overhead from time to time on the sets.
Kona side: Wave heights knee/waist high are expected today.
South: Breaks open to the south-southwest swell could get up to knee/waist high but probably no bigger. The best spots open to the tradeswell could reach chest/head high or slightly bigger on the sets.
A east-northeast trade swell is showing for windward coasts this week.
A new small south-southwest builds Tuesday and peaks Wednesday into Thursday before fading 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.
