Yes, it can get 95-100 degrees here with 100% humidity and a heat index of 100-110 degrees. My coop is fully enclosed with ventilation and a pop door and a covered/shaded chicken run and they did fine. Chances are they won’t be inside the coop during the day all the time anyway and your area looks pretty shaded.
So if you ever decided to wall up the open side
Of your coop, as long as you provide good airflow you’ll be fine. Chickens won’t sit in there and bake. They’ll try to cool themselves off with a dust bath or seeking shade. And if you keep fresh cool water on hand regularly and maybe provide some electrolytes they will be fine. My conditions are close to yours at times and they did not overheat.
As far as predators go, I would think hawks are not the only critter around there who would get after your chooks. But raccoons, foxes, coyotes, stray cats snd dogs too.
Foxes and dogs will dig to get at your flock, coons will climb and try to find a weak spot in your fencing or an opening big enough to squeeze through, they only need a few inches for that, or one that’s big enough to pull a chidown through, piece by piece if they have to. They’re persistent and clever predators.
So for the safett of your flock you may want to ‘think like a predator’ and see if there’s anyway one could compromise your chicken area and get after them. But that’s just my .00000067 cents worth of limited advice!
