Seems a bit high under those conditions, but not too high. Are you driving with A/C on? My 991.2 seems to run a bit cooler with A/C on. I think the radiator fans run constantly under those conditions.

In traffic the car heats up very quickly. Radiator fans only can do so much, have to be moving to really move the air and cool the car down. 100 C is nothing, I've seen higher in summer traffic.
