Big Island Surf Forecast

Hilo side: Messy waist to head high waves are expected today with occasional plusses at the best breaks.

Kona side: Wave heights of knee to thigh high are expected. Standout spots open to the south could get waist high waves on the sets.

South: Wave heights of ankle to waist high are expected. Messy trade swell is expected for the southeast coast up to waist or even head high.

A new west-northwest swell is building and expected to peak Tuesday for the Kona side. The swell begins to fade Wednesday.

A northwest boost is expected late Wednesday/Thursday due to a storm in the Bering Sea. This should peak late Thursday hold through Friday and then begin to fade. A small bump out of the northwest is also expected next weekend.

Tradeswell is expected to hold for the Hilo side this week. Conditions will be sloppy due to the onshore flow.

Our current southerly swell is expected to continue fading Tuesday with another small bump expected midweek. A possible reinforcement swell is on the horizon for next weekend.

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.
