A fun south-southwest is forecast from the 14th to the 17th from a storm system that recently developed near New Zealand. This swell will begin to ease Sunday into early next week. Another south-southwest is forecast from the 19th to the 21st.
A series of small northerly swells are expected this week. The largest is forecast to fill in Friday. None of these swells are expected to produce High Surf Advisory-level waves.
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.
