If it's only at idle (stopped in traffic), then it's airflow over the condenser.
The clutch fan could be weak (viscous couple wearing out), the condenser could have debris in it...or you might need to add a second (or bigger primary) electric fan.
I notice the same issue in my truck...worse so in the '07 Expedition EL we recently purchased. it's not horrible, but the A/C performance suffers when the truck's not moving.
It was an issue in my Silverado SS that I owned before my Titan - I upgraded to an electric fan setup on it and the A/C cooled noticeably better at idle. I added the fans for performance, but the A/C improvement was a nice bonus.
