>>874928Meteorologist pro-tip on that: if your beach camp site is near a major airport (like, within a few hundred kms) check the local TAF to see if a seabreeze/landbreeze setup is going to occur. You'll see the changes on there.
I guess it doesn't make much of a difference but if wind matters to you it might help. I've always found camping slightly off the beach will help hide you from the worst of onshore flow.
Remember water is a low-friction enviroment for wind so if the winds coming from that direction it will usually be stronger.
