If there is not a lot of air turnover, you could try a dehumidifier. Otherwise heat is the only real answer.
Its a pole barn with plenty of ventilation, I don't think a dehumidifier is going to help much.

When I had mine in an unheated shop, I kept 30weight ND oil on them and covered them in canvas painters tarps and put inexpensive Compact Fluorescent Bulbs under each tarp where it couldn't touch anything flammable. It worked well until I could build an insulated room in the shop for them. Here in Alabama, it gets cold and then a front comes through with a big warm up and lots of humidity. It condenses on everything, even the shop floor and metal doors. My truck drips puddles parked in the shop.

I have much of the same weather here, and it is a pain in the butt with these warm fronts moving in. It fine when its cold, and stays that way, but the weather is what it is. I was out in the shop, and out in the sheds today with a coffee can filled with hydraulic oil, and a paint brush, giving everything that could possibly rust a good coating.
If your using WD-40, note that that stuff will absorb moisture, and can cause your stuff to rust. I know many disagree, but I know first hand, that stuff is not the greatest stuff to protect your tools from rust. Your better off using oil, than WD-40.
There is lots of other products on the market to protect from rust available in spray cans, you might want to look into these. One other thing to think about is looking at areas that you don't normally see, If they are bare metal, and exposed, you know what happens.
