Swell Summary
The most recent southwest to south swell will be slowly falling through today with a possible small reinforcement filling in later today into early Friday. The next small southwest south swell may arrive toward the middle of next week. A small, medium period northwest swell is expected to reach the islands later this weekend to then be followed by a series of small, similar to slightly higher period northwest north swell energy through next week. East facing shore surf will trend up to seasonable levels the next couple of days with the return of fresh trades over and upstream of the state.
