    Solids can be wet. I think that you meant water can be dry? It is pretty dry at forty below zero F.

    I know of one technical context for "wet" --- liquid in a solid container either "wets" the walls or not (for instance mercury at normal temperatures does not "wet" glass, but water does).
    The OP was most likely referring to the sensation of wetness, which I believe comes from supersaturation with water vapor. In that sense, when you touch ice, it will feel wet first of all because anything you sweat out of the relevant pores will stay there, second of all because there will be a bunch of water that liquifies on contact with your skin.
    And then you talk about -40 degrees, when I believe most human hands would freeze themselves before successfully melting a little bit of water... so I assume all of my above discussion can be ignored in that context (probably for anything below -37 centigrade in fact).
