Boiling water temperature? Surely not.
It's largely to do with the ability of air, compared to something like water, to transfer heat - with air being relatively poor at it. Hence why comparing air at 100 deg C and water at 100 deg C isn't a good comparison. Water will trasnfer it's heat much more effectively than air, hence you can survive in dry air at 100 deg C, but not water at 100 deg C.
Same principle applies for cold water, being sumerged in to 10 deg C will feel much colder than being in 10 deg C air because it will much more efficient at transferring the heat away from your body.
