Swell Summary

Small to moderate west-northwest swell will prevail through Friday, followed by a pair of larger swells this weekend and early next week. The current west-northwest swell peaked around 4 feet 16 seconds and will drop slightly on Thursday and Friday. A storm low deepening south of the Aleutian Islands today will generate a larger north-northwest (330 degrees) swell that will build rapidly on Saturday and peak through Sunday, producing surf near High Surf Warning levels along north and some west facing shores. Another storm low is expected to develop closer to Hawaii this weekend and generate a larger swell from 320 to 330 degrees. This swell will likely produce surf above warning thresholds late Monday and Tuesday.

Surf along east facing shores will continue to sharply decline through Thursday as easterly wind swell decreases. East shore surf will be well below seasonal average through the weekend as winds over and upwind of Hawaii remain weak. Some increase in east shore surf is possible early next week. Along south shores, wrapping easterly trade wind swell will drop off Thursday, and surf will remain very small through the rest of the week.
