Yes it has to be wet in order for it to get hot in the middle. When they are baled wet the center doesn't dry and it will keep getting hotter until it combusts. This is less of a concern in square bales and a greater risk with very large rounds that are not dried properly. Normally farmers let their hay dry properly. We don't keep hay outside, we have the hay loft above the barn.
