Cannon Beach is an annual tradition and every year I think that I'm going to post what we are bringing but I don't.  I frequently look back at posts to remember how we did something or where we went.  It my memory because the one in my head doesn't always work.  So here is the list:

Short sleeve shirts (many)
1-2 long sleeve shirts (the beach can be windy)
shorts (many)

socks
pajamas

towels

wet suits (the ocean is cold and we rent boogie boards)
