The RH is high in the morning but it dips below 50% in late afternoon when the temperature is 104F. The trick is to move at a leisurely pace from air-conditioned house to air-conditioned car to air-conditioned workplace, and back again for the warm half of the year, as I recall. It's also a good place to practice taking siestas. I grew roses in Austin in similar weather. They liked it there, but they were all pretty much immune to blackspot. One digs holes for plants in fall or early spring. One sits in their shade in the cool of late evening, breathing deeply air that is thick with confederate jasmine blossom (trachelospermum jasminoides). Or maybe one sits inside in front of the air conditioner with the coolish air blasting one's sweaty brow. Spring and fall are long, and winter doesn't even exist except for the few days in January when a "blue norther" sweeps through. That's how I remember it, anyway.
