What is this strange smell sensation that happens to me every Fall around this time?

Every Fall for as long as I can remember, right around now, I have a strange thing happen to my sense of smell. There is an omnipresent kind of background smell. It's musty. It's not strong. It's not really a smell in the way other smells feel. It feels more like it's there under the other smells, and I smell it everywhere (inside, outside, work, home, you name it) and all the time. I especially smell it when I breathe through my nose, and I smell it when I normally don't notice other smells (i.e. I don't normally notice the smells of my house, but I notice this smell when I'm sitting there).
It generally hangs out for a month or two and disappears. It's not an unpleasant smell but it's not vanilla and lilacs either. The only time I spent October in the Southern hemisphere, it wasn't there.
Does anyone else have experience with this? What causes this?
