Out of curiosity, what do you believe is too hot for tomatoes? Mine do much better with daytime temperatures in the 90s than they do with daytime temperatures in the 70s to low 80s.

We had daytime temps in the 95-102 range in july and august, with no rain and hot nights. I am not an expert, but I have been told that tomato tend to not produce flowers when nighttime temps stay above 70. No flowers means no pollination and no fruit. And my observation seems to support that theory. When I lived for some time in the tropics, tomatoes used to do better in winters there, maybe for the same reason.

Temps started getting lower in late August and the flowers came back, and I now have a decent set of fruit happening - although it is a race to harvest them before squirrels/mice/birds take a bite out of them.
