Yep. The dash indicator varies greatly from car to car. I wouldn't sweat it unless the gauge goes into the
red. In the current heat (90+ and humid), I hit A and L on the highway sometimes, specifically when I am in traffic and running the AC. No biggie.
If you are really worried, have someone hook up an OBD-II scanner and monitor the
ECT value - that comes from a much more accurate sensor. I've done that and know that O is 180 degF and L is 210 degF on my car. 210 is hot, but not extreme or dangerous especialy in this weather. Now if it was doing that in the winter, I'd be more concerned.
It wouldn't hurt to make sure the radiator is clear of any debris that would restrict airflow through it.
