Tradeswell is expected to hold for the Hilo side this week. Conditions will be sloppy due to the onshore flow.
A small south-southwest is expected to peak Thursday and hold through the end of the work week before slowly fading through the weekend. Nothing much on the horizon out of the South Pacific.
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.
