Today I sailed 3rd Avenue on a 4.2 and 86L board. Slightly overpowered at times in the channel, which boasted the biggest swell I've ever seen at 3rd. I believe the ebb was 5+ knots... some occasional sets that were like big brown school buses trudging across the bay. Very cool.
I guess it was kinda cold, but I got away without gloves or boots and a 5/4... The sun was showing bright which I think helped quite a bit.
