Swell Summary
Surf along south-facing shores will very subtly decline Monday as a very small, medium period south swell lingers. A slightly higher longer period south swell will arrive Tuesday, then build surf to near early summertime averages through mid week before slowly fading out Thursday. A large fetch of 40-plus knot winds currently generating 25 to 30 foot seas southeast of New Zealand is aimed toward Hawaii along southern great circle directional routes. This should push in a significant size, long period south southwest swell later this week. South and better exposed west-facing shore surf will begin building Friday and may peak at or slightly above high surf advisory levels next weekend.
North and west-facing shore surf has and will hold through Monday in response to the latest small north northwest swell that arrived this past Friday. A late season storm force low in the northwest Pacific low moving just south of the Aleutian Islands will focus its energy southeast of its easterly track. The resultant small, medium period swell will arrive late Tuesday and gradually fill in around the islands through Wednesday. Above seasonal average north and west-facing shore surf is expected Wednesday into Thursday.
East-facing exposures will still experience a short period wind wave chop the next few days. Seas will become less rough into mid week as trades begin to slightly ease.
