Swell Summary
The small, medium period northwest (310 degree) swell that peaked earlier Monday will be gradually subsiding through the day. A similar size, medium period northwest (320 degree) swell will arrive Thursday. This swell will only pick up north and west-facing shore surf by a foot or two as it peaks Thursday night and then falls through Friday. Elevated wind wave chop along eastern exposures generated from a large source region of moderate trades upstream of the islands will persist the next few days. Very small early to mid week bumps along southwest and southeast shores, from either background energy moving in from the Southern Hemisphere (190-210 degree) or from trade wind swell wrap (040-130 degree), respectively, will keep south-facing shore surf around waist high, at best. The combination of the shorter period trade swell and the longer period background south swell will sustain slightly higher surf heights along many eastern and southern Big Island exposures the next few days.
