I have been paddling here since 1988. iT IS GREEN and ok at 18k. At 20ish a pile is formed, at 24ish a big pile
Shack and SC, my point exactly. I grew up in Junction, and have been paddling since 93ish. Surfed Big Sur every year from 94-96 (could be off, but three years straight).
If it is under 24k, then I think it will be nearly impossible to surf in anything modern. It was hard to surf in Kintecs and Super Sports. Above that, and I think the newer boats are going to kill it. I remember my first air while surfing was here, because on surfers left you can carve out of the pile and down the face where boils roll over the front lip. With enough speed you could bounce a super sport a few inches in the air. At the right level and with a flat bottom boat I think you can go huge. At 18k, bring the frankenstien.
Thus, I wouldn't bother showing up until 24k, unless you want to bring the long boat... its all you. My take, 1/2 hour front surfs became boring after the first time I did a cartwheel.
The glory of some of the old playspots is dissapearing with the advent of short boats. Westwater is a prime example, where a 7'5 and up boat was great, and now the newer freestyle designs just can't catch the same waves. But, we can play more features now and do much cooler shit in the short boats.
