Fr. I live literally 20 minutes from mountain peaks on a major US interstate that close during winter because of heavy snow and it was 112 today when I got in my car today.
There's ways to mitigate the amount of water used and it's retention in the soil.
I also frequently have temps in the 100's in the summer here - it's meant that there's just certain things I can't grow and some that are risky. But there's plenty of veggies that can handle that kind of heat.
