The difference between 4 ft @ 15 seconds and being totally flat is just a litttttle too close for comfort for me. Actually, it seems many times they ARE the same thing if the tidez aren't just goldilocks right. People go crazy over these types of swelles, it's crowded as ****...all for a mushy closeout every 10 mins. Give me some consistent 8 second wind swelle and wind that's not too terrible and I'm good. So frustrating seeing swell on the buoy but none in the water.
