I have a Grand Am 2.2 Echotech, during the really hot weather we are having in NC I have noticed my water temp gets up to 205 and stays there during city driving, on the highway it goes down to 195. I looked and both fans are running. Water level is normal. Is 205 too high?

Are the fans blowing while the car is in motion?

205 is indeed normal,more efficient than 180. I'd not be too concerned especially this time of the year.
205 sounds about perfect.
just fine for a GM. Ive seen many run a little higher than that in hot weather.
The 205 in city driving isn't bad, and 195 on the highway is ideal. Normal temps. Coolant maxes out around 230 (as A_Harman mentions).

No, 205 is fine. Many engines today are expected to run at 210. 215 to 220 in traffic on a hot day is not cause for alarm in most cases.
230... that's heading toward trouble.

According to the charts, 205 with a 50/50 water - antifreeze mix is ok.
Provided your coolant isn't boiling, and the motor doesn't misfire, all is well.
High test fuel does usually work better in extreme heat.

the high speed fan don't come on till 235. 205 is the lower end of normal. I don't like to get em over 240
normal and good
Actually, I was wrong. Coolant doesn't always boil at 230, but it can indicate the oil temp is getting too high.
That question reminded me of the old, air cooled VW bus / East Saint Louis joke. Goes something like:
180F> Too cool. Is the thermostat still there?
180-210F> Peachy
210-250F> Can live with it. Many buses w/type 4 engines get that hot under
loads in summer.
250-280F> Something is wrong & must be fixed. However viscosity of good
synthetic oil should be fine. If it's dark and I'm in East St. Louis -
I'll keep driving!
280F> Better stop - unless the oil pressure light is on, and just let the
engine run.

How old is the antifreeze/coolant?
Sounds perfectly normal to me.
