Swell Summary
A moderate mid-period south swell will continue to steadily decline over the next few days with below average surf expected by the weekend. Background southerly swells will keep surf from going flat over the weekend into early next week. A gale low just east Australia will shift east of New Zealand over the next couple of days in a more favorable position for more consistent southerly swells for Hawaii late next week. Forerunners from the captured fetch from this system could start trickling in by mid week and gradually build through the rest of the week into next weekend, generating above average surf.
Near seasonal average surf generated by former tropical cyclones will gradually fade to below average by Saturday and hold into early next week as trades locally and upstream remain disrupted.
Tiny surf along north facing shores will continue to fade tonight as the small swell from Lowell moves through.
