Big Island Surf Forecast

Hilo side: Surf heights are expected shoulder to head high early in the day. The best breaks open to the swell could see even bigger waves on the sets.

Kona side: Surf heights are forecasted to be knee to waist high. Possibly to shoulder high on the sets.

South: Southerly spots open to the east-southeast could get knee to shoulder high waves.

Our current swell is on a decreasing trend and expected to fade Wednesday into Thursday.

Late Thursday we expect a west-northwest to start building, showing a bump in size by morning. This swell is expected to show well for the Kona side. The peak is expected to take place late Friday or early Saturday.

A larger west-northwest to northwest swell is expected early next week pending development of the storm.

Nothing to get excited about out of the SPAC. Late next week we could possibly see some fun waves from a storm expected to develop near New Zealand.

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.
