Hilo side: Wave heights for spots exposed to the large swell are expected to be head high to a bit overhead today. Spots without direct exposure will be smaller.
Kona side: Wave heights are expected to be waist/chest high today with the best breaks bringing in shoulder/head high waves early on.

Our early season south-southwest bump is expected to gradually fade for southwest exposures through Friday. Another swell is on its heels for next weekend and peaking early next week.
Small short to mid period swell is expected for northwest exposures through today. This energy will hang around Wednesday and Thursday before fading Friday into Saturday. Another swell is possible this 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.
