Swell Summary
Surf across most shores will be below seasonal average through the week. Moderate and choppy east shore surf will persist into Wednesday, and a decrease in trade winds will cause surf to decline Thursday and Friday. Moderate surf along south facing shores will slowly decline Monday and Tuesday as the current south swell drops. A small southwest pulse out of the Tasman Sea could produce a slight rise in surf Friday. Aside from trade wind wrap, north shore surf will be minimal through Wednesday, and a tiny northwest swell will be possible Thursday or Friday.
