Swell Summary
Surf heights along east facing shorelines will remain solidly within High Surf Advisory (HSA) criteria through at least midweek. The HSA is in effect through Wednesday night as strong upstream trades are expected to persist.
Surf will remain small along north, west and south facing shores through Saturday, as no significant swells are forecast into the weekend. However, the arrival of a small medium-period northwest swell may bring a slight uptick in surf along north-facing shores late Wednesday through Friday.
In the extended range forecast, forerunners from the next moderate to large, long period north (010-020 degree) swell appear to arrive by late Sunday night, building swiftly to advisory levels by next week Monday, and then slowly declining into the middle of next week.
