Gary, it could have been me that mentioned about cherry toms doing better than larger tomatoes in the more extreme heat. It has to do with blossom set or drop and the average daily temperature. If you have night time temps in the 90s, then cherry, grape, and berry tomatoes will continue to set fruit while the large slicing tomatoes or the Romas will sulk and drop any blossom. It's a different temp for different varieties.
My absolute best summer long volume came from tomato seed purchase from Johnny's Selected Seeds, I think. Maine Tomato Berry. Now why my ex bought DownEast tomato seed for growing in Florida, I do not know. Contrarian, that fellow. But over ten years, that was the only one that continued to fruit from spring well into fall. I dried a lot of tomatoes back then, and the flavor of these tiny berries fresh or dried was pure pleasure to this Jersey girl.
All of the Solanacaea: peppers, tomatoes, eggplant, tomatillo, and others (excluding potato which I never tried to grow through summer) had issues with extreme continued heat. Peppers and eggplants did better than tomatoes overall, but eggplant from India or Thailand was more tolerant than Italian types. I've read academic papers on the productivity of plants in this family, as we all do?

They just confirmed my general observations over the years.
Everybody's situation is different. Not just the climate or the soil, but the techniques and the practitioners, the microbes and marauders. No toms for me this year at all. Root knot nematode coupled with summer move. Maybe in Autumn I'll be settled enough to grow some in large tubs at least. I'm buying all my tomatoes at farm markets and ethnic groceries. Depressing and interesting at the same time.
