Hey Rick,
Lori and I have been out kitesurfing that exact spot on the oregon coast last two summers, it is a blast!

But it really isn't that cold at all, water in the 58-60 deg range and air in the 70's if the sun is out
I was easily in my 3/3 NP steamer and Lori in her 4/3 full
Waves have long periods so it is pretty easy to get out
