When is coolant temp too hot. About 216

I expected a little increase with my slight build. I now have the AC hooked back up and I'm running about 216 yesterday. It was 104 outside here yesterday and of course I was running the AC. I have a new wp, 180 ts, new radiator, 50/50 mix. It seems to always run between 200-216 all the time. My gauge seems to read the same as the temp gun. At what temperature should I be concerned.
