Swell Summary
The recent moderate size, medium period north swell will be slowly declining through the day. Today's north surf heights will only subtly lower as an overlapping small, but slightly longer period, northwest swell fills in through tonight. A slightly larger, shorter period north northwest swell will arrive Thursday, peak Thursday night into early Friday then fall over the weekend. A large northwest swell is timed to reach the island chain Saturday night and peak Sunday. This swell will increase early week surf heights to above High Surf Advisory thresholds, possibly as high as low-end High Surf Warning levels. Looking further out to next week, a potentially even larger swell is possible Monday night into Tuesday.
A few slightly larger, medium period south swells will begin arriving today. These swells will bump south shore surf up by another foot or two through the remainder of the week.
Surf along east facing shores, with the exception of more northern exposures experiencing a higher north swell wrap, will continue to fall through late week in response to a weaker trade wind regime.
