Hilo side: Wave heights are expected to be chest/head high in the morning and quickly building in the afternoon to double or even triple overhead at the best breaks on the sets. Trade swell is waist/chest high.
Kona side: Wave heights are expected to be knee/waist high sets in the morning with norther exposures catching wrap out of the northwest up to chest high or even a few feet overhead.
South: Out of the southwest just knee high today. Trade swell brings waist/chest high waves.
Trade swell is expected to remain pretty small at waist/chest high or less.
Swell from tropical system Pali is expected to slowly continue fading through the week.
A new south-southwest swell is expected for the weekend with waist/head high waves, peaking Sunday.
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.
