Swell Summary
A small, medium-period northwest swell will arrive overnight and provide a small boost to surf along north-facing shores on Friday. A moderate, medium-period north-northwest swell will build late Saturday and peak around seasonal average on Sunday. As this swell declines on Monday, a long-period west-northwest swell will arrive, maintaining small to moderate surf into the middle of next week.
Small background level surf will prevail along south-facing shores through Friday. A small to moderate south-southwest swell is expected to boost surf to around seasonal average this weekend into early next week.
Along east-facing shores, trade-wind swell will continue to decrease through Friday, though a small, medium-period northeast swell may maintain small surf through Saturday. Aside from wrapping north- northwest swell in exposed areas, east shore surf should remain below seasonal average much of next week.
