    Doh!
    I did a bit of research and answered my own question. No is the answer.

    Basically, it would have to have a constant steady input of water vapour (basically a thin atmosphere), or much colder temperatures.

    My impression was that the water found on the moon was adsorbed in the regolith. On earth, clay retains water molecules at higher temperatures.

    The basin at the south pole might have lava tubes. The inside of tubes on the poles should be colder than tubes at the equator.

    Honestly I do not know what is on the surface of a lunar lava tube. It must have a surface. Would be nice to have a sample.
