Doh, you're totally right. Although still, in the desert, there isn't much water in the air even if it's really hot. https://www.engineeringtoolbox.com/moistu

  Easy to get confused because humidity % tends to be higher at a lower temperature (morning dew for example).

    Why is this?

      Say you have a given amount of water vapor in the air. Relative humidity as a percentage reflects the amount of water vapor in the air compared with the maximum amount of water vapor the air could hold at that temperature (and pressure). The amount of water vapor the air can hold depends on the temperature, with higher temperatures able to carry more water vapor. As the temperature goes down, the amount of water vapor stays the same while the amount the air can carry decreases, so the relative humidity goes up. https://en.wikipedia.org/wiki/Relative_humidity https://en.wikipedia.org/wiki/Relative_humidity

      I believe it's simply a matter of colder air increasing in density so there's less space for the water vapor. When the air heats up, it expands and can hold more vapor in the increased volume.

  There's more water vapour in the air in the middle of the Sahara desert than there is in the air in the middle of Greenland while it's actually snowing.
