Default Still overheating! Help

I been trying to figure out the overheating issue and it seem to get worse
I have a 2007 hummer h3 with roughly 126k miles

I replaced the water pump, radiator, hoses, thermostats, and even radiator fan clutch. I also replaced the temperature sender not that long ago

today in Florida temp was hot around 95 degree
I am on the traffic light idling I am at 235 degree, ac running and getting close to the red line

what’s going on? I heard some folks can be at 100 degrees and they barely go over half I am getting close to the red . I don’t know what’s wrong or how to figure it out. Any help I would appreciate! I am tried of trying to fix this issue and it’s really getting frustrating

Did you clean the ac condenser and radiator fins?

Light passes through restricted air flow! Properly clean both sides of the condenser & radiator before you throw more parts at it.

Try some of that Wet'r water or the like that you add to the rad. Put an actual louvered slat opening on the hood not the wimpy black plastic piece.
Just an example have zero personal experience with this product!
