Mike, what are high temps for you? I think roses can become acclimated to very very high temps. I have all the roses you named except Colette and Bill Warriner. Those two died in a super wet summer 3 years ago.
Chihuly, Janice Kellogg and Polka have struggled here this summer. Chihuly also struggles in excessive winter cold. I have 2 and they both look awful, and one is in a very protected spot. Janice Kellogg was a very small plant when i bought her, so that may be her problem.
Our temps were over 100 for 5 weeks, and the roses did great. We had strong winds and no rainfall. We did not have humidity of more than 25%, though. Most afternoons, the humidity was around 15%, desert levels. No blackspot issues here, that's for sure!
Rainbow Sorbet, almost all the Austins, Home Run, Julia Child, Scarlet Carpet, the new AARS yellow rose, whatsitsname, and Ketchup and Mustard all kept blooming through the heat. The blossoms were smaller than normal, but the shrub itself looked fine. Just now I see they are putting up larger buds.
The yellow Austins in particular were blooming machines this year. Graham thomas, Molineux, Charlotte, Golden Celebration, Teasing Georgia, Jude the Obscure, Port Sunlight, Evelyn, Charles Darwin, all of those were just wonderful here. Some of those were fairly new in my yard and really didn't get any rain and little irrigation. Westerland, Jacob's Robe, and Autumn Sunset do well no matter what the weather throws at them. Carefree Sunshine, Sunny Knock Out and Yellow Brick Road were excellent in 100% full sun. Our temps don't fall much at night--only to low 80s for most of the summer, so the roses really don't get much of a break. I'm guessing you do get a nice cool down at night.
Winner's Circle, Can Can, Milwaukee Calatrava, Lemon Meringue, and Morning Magic were all constant bloomers on an east wall, protected from the wind and afternoon sun. Those are all Radler's roses and have only been in the ground for 1 year. Cl. Valentine's Day held its lovely deep red color even through the hottest, sunniest days. I have 4 of it, and all were fabulous. Summer Sun and Lady of Shalott were new and they have been blooming for the last month.
Someone else will have to vouch for what happens in a humid situation. In past years, we've had rainfall at night that caused some blackspot. I don't have many hybrid teas just because of that, so I can't tell you how they would do where you are.
Hope that helps.
Remember that children, marriages, and flower gardens reflect the kind of care they get.
