If I have AC on and driving in traffic it's always sits at the end of 0

Is it high? what temperature is the mark after 180?

Thanks

I bought this: http://www.scangauge.com/
It will show real time read outs of all sorts of things.
It was informative because it showed that my "cold air" intake was hotter than stock, and that the engine temp was really high.
Also it help me prove to myself that the low temp thermostat and redline water wetter worked in lowering my water temp by 20 degrees.
