Usually surface air, mostly because the temperature sensor is really really
slow to register.
So the first sample - if it has a temperature at all, of course - is
usually ambient temperature of the dive computer before the dive started.
Now, is it "air"? If you keep your dive computer in a camera easter bucket
like some people, obviously not. And if you are on the surface for a long
enough time, then the slow temperature sensor will basically give you
surface water temperature.
But normally? Air temperature is likely the closest description. Certainly
not guaranteed, but then, it would usually be even worse to call it water
temperature..
