A mix of small medium to long period S swells maintains small surf along S facing shores for the next several days. The aforementioned long period SSW swell will favor increased surf along S facing shores through today. Additional medium to long period S swell arrive through the week. Meanwhile, trades maintain choppy short period surf and fresh easterly swell through the week.
