Hilo side: Wave heights are forecast to be head high or more today for the best exposures.
Kona side: Wave heights are expected to be waist/shoulder high today with waves up to head high on the sets.
South: Wave heights are expected to be waist/shoulder high today with waves up to head high on the sets.
A reinforcement of west-northwest swell is filling in with enough west to bring some wrap to the Kona side. Heights will maintain Monday at the best exposures and begin to ease in the afternoon. By Tuesday the energy is down to leftovers.
Another round of west-northwest is forecast for Thursday / Friday, beginning to build late Wednesday. This swell has a little more west in it so that will be more favorable for the Kona coast.
The SPAC is quiet but another small sweet is possible around the 22nd.
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.
