Swell Summary

A couple of small, longer period west northwest swells will travel around the islands in the coming days. The first of these swells will be arriving today and be leveling out from Sunday night through Tuesday afternoon. The second set of similar low west to northwest swells will be moving through around mid week.

In response to strengthened trades over and upstream of the islands, east-facing shore surf will increase going into early next week. Recent satellite observations verify a large region of strong trades upstream of the state that will likely generate a long enough fetch region to produce near advisory level surf along eastern exposures by Monday. Energy from far Southern Hemispheric gales clipping the islands this weekend will provide a subtle boost to south-facing shoreline surf.
