During the winter...you might be surprised...at least in Cleveland...by just how dry it gets. I'm not that familiar with your climate, but I live in Maryland, and this past winter was especially brutal -- with regards to dry air. It was amazing how quickly it sucked the moisture out of the wood. I wouldn't be as concerned during the other seasons...but definitely...think about the winter months...especially if you use a fireplace of any kind in your home. That can really dry out the air.
