In summer the pitch of the treble rises, in winter it drops, while the bass stays the same, more or less. Sometimes only the middle region of the piano goes up and down, but also often all the treble strings do. I allways think it has to do with the place of the bridges. The bassbridge is placed on a more ridgid part of the soundboard, so it suffers less from humidity swings. However, maybe the strings themselves are also an item. Because the difference between the first treble, and the last bass string is often evident, even if they are both part of the treble bridge. Don't have an explication for that.
