Screen Shot 2016-07-20 at 8.30.24 PMOur current south-southwest swell is still fading with a small swell mixing in. A new southerly swell is expected for around July 30th.

Quiet in the North Pacific at this time.

Trade swell will fill in through Thursday. Darby swell is expected to peak Friday before slowly fading through the weekend. Estelle should also generate swell. Will keep an eye on the development and bring you details as they become clearer.

Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
