According to the National Weather Service in Honolulu, the current south swell is a bit stronger than forecast, generating surf slightly higher than forecast. While this advisory expires after tonight, another south swell expected to peak late Saturday into Sunday will boost surf heights above advisory threshold again.

Areas impacted include South Kona, Ka‘ū and Puna Districts. 

Surf is expected to be seven to 10 feet. There will be strong breaking waves and currents that will make swimming dangerous.

Beachgoers are advised to heed advice from ocean safety officials and when in doubt don’t go out.
