Swell Summary

A series of small to medium period north and northwest swells from Aleutian sources are expected to increase surf heights along north facing shores through Friday. Medium range guidance shows a cut off low forming far north of the state on Thursday and Friday, sending a north swell towards the islands arriving by Saturday night.

The current south swell will continue trend a bit lower today before another small background south swell fills in on Thursday with slight increasing trends expected on Friday and Saturday. A slightly larger, medium period south-southeast swell will arrive by early next week.

East facing shores will remain small over the next week, with a potential for a small north swell wrap by Sunday.
