I live in the Mojave, and I stopped trying to grow tomatoes here. Just too darn hot. I would grow Big boys, and they ripened as cherry tomatoes! Sure, they were tasty, but they never seemed to want to get to full size before ripening.

Now I plant chili peppers, which LOVE the heat/sun. The season has ended, so I'm starving the plants and letting what fruit I do have get red on the vine. Then I'll pluck and dry 'em. Hopefully, the spice will intensify, if rumors are true. We'll see.

I don't feel so bad now, after seeing your picture above!

Yep, it looks like a very small tomato .

Fear not, you can grow tomatoes in extreme heat. Here's two quick tips.

First, there are now varieties that are created to be heat tolerant. Seed packs ought to have some type of message on them.

Second, but it might take a bit of work. Find a place where the plants only get morning sun. You mentioned container plants for the determinants. Put the container outdoors in the morning and then then bring it indoors, allowing it to get cool sometime in the afternoon. Repeat and grow.

I know it won't work for most people who spend the day out at work. Just a suggestion.

It was a cool cloudy wet Spring/Summer with highs on some days in July in the 60s. June was well below average with weeks in the 50s. As a consequence, we suffered slow growth/ripening and high fungal disease issues. I still got a good harvest, but some of my tomatoes were shot by September.

Our Farmer's Market this year was really lacking. No one even had tons of zucchini like usual.

The predictions about stuck jet streams seem to be coming true. There's been a few good articles on the sticking of jet stream ridges and troughs. http://science.howstuffworks.com/nature/climate-weather/atmospheric/changing-climate-jetstream-weather-gets-stuck.htm
