We've been in the 100's in where I live in SoCal for a few days now and everything is still setting fruit.

There is one lone tomato on my plants. Lots of peppers but some of the maturing fruit look like they've been damaged by the sun.

Once the nightime temps reach 73 degrees the tomato plants will generally stop setting fruit

Our night time temps are still in the 60's.

Soil temp is as important as ambient temps, so if you can regulate that soil temp by mulching, peppers and toms can still keep pumping them out. My plants are doing fine with the 3-4 inches of mulch and some shading from 1-4pm. Of course, we don't get the real high temps for weeks at a time until later in the season.

Like Kevin said, keep in mind that day time air temp is far from the only contributing factor to Blossom Drop or to the lack of it either. It hasn't been 95-100 for the full 24 hour period.

Just count your blessings and keep your fingers crossed but don't jump to any conclusions.

And the regional reported air temps or even the temp recorded on a thermometer hanging somewhere nearby isn't necessarily accurate as far as the plant is concerned unless the thermometer is hung in the middle of the plant. :-)
