Hilo side: Wave heights are forecast to be shoulder high or more today for the best exposures and slowly starting to fade at the end of the day.

The High Surf Warning has been extended through this afternoon as our current large west-northwest swell ended up filling in slightly later and a few feet bigger than expected yesterday. The swell will continue to slowly fade.
A second round of large surf is forecast for next week between late Tuesday night and Thursday. Will keep an eye on it. This swell could possibly start building by Monday.
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.
