Swell Summary
A declining northwest swell will be reinforced by a large pulse of north swell through the day today. Surf will peak along north and some exposed east facing shores early this morning close to the High Surf Warning level. A High Surf Advisory (HSA) remains in effect for most north facing shores through tonight for north facing shores of most islands as well as some windward/east facing areas that will be exposed to the northerly swell. Looking ahead, a storm low in the distant Northwest Pacific will produce a moderate, long period northwest swell that will arrive late Monday through Wednesday, with peak surf below HSA levels. East shores will experience some wrapping north swell during the next few days, followed by moderate, short-period wind swell through much of the coming week. South shores will remain seasonably small.
