I don't take any notice of the outside temp reading until I've been driving for a while.
There's one external sign about 5 minutes from home so I see it both on the way out and on the way back.
There's another about 15 minutes further up the coast and one on the northern approach to Brisbane which is 60-90 minutes away. I've been looking at these three for nearly 3 years now and only noticed the variations after I got the i30. The nearest one can be firly accurate or up to 5 degrees different on the same day but with no consistency as to whether I'm on the way out or back.
