Post Ida, glassy waves, planes, wind, and fins

I took my NSP 8'7" down to the beach to try to ride what looked like decent waves from the cross cam. There was a strong northerly wind that was pushing the waves down and the water out so there was a some good sandbar interference. I also made the mistake of untying my surfboard from the roof of my car and leaving it there while I was putting on my wetsuit. A strong wind blew and now I have a nice sized lump on my head from getting hit with my board. The beach was unlike I've ever seen it before. It was littered with shells and sand dollars pretty far back onto the beach. It was beautiful, the beach was pretty much deserted save the few surfers and shell collectors out.
Waves were glassy and breaking in nice lines, the problem was that there were the old sandbars out 50-75 yards out from the shore that got really shallow. There was several times that I dug my fins into the sand bed before even catching the waves. Sometimes the waves will be powerful and tall enough that shallow sandbars won't be a factor, but it wasn't true today. Also, the northerly wind both reduced the size of the waves coming in and pushed the water back into the gulf, making water levels lower and causing these shallower sandbars. It was really amazing how much effect the wind had on the water level. There was a time when the wind stopped blowing and, before I knew it, the water level jumped from 6"-3' to about 3-5" over the sandbars. The waves started increasing in size, and I was actually able to ride several ok waves before the wind picked back up and knocked everything back down. The waves would have been ideal for surfing in they had been bigger. I also saw a dolphin cruising around about 200 yards from the beach. I dismounted my surf go pro cam and snapped a picture. It really didn't turn out, the dolphin was half submerged by the time I got the pic, and the fish eye lens distorts it, so it is about as sketchy as a big foot photo. I'm also attaching a video of probably the best ride of the day, which isn't saying much as you'll see.
