A recent storm near New Zealand has brought some fun waist to chest high waves for southern exposures. The swell should hold through Monday. A small new south-southwest is expected midweek. A fun sized swell is possible the middle of next week.

If the storm develops as models are indicating, we could see a west-northwest swell late this week.

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.
