What varieties would you folks say are the most heat tollerant? Will still set nice fruit mid to late summer( July -Aug )

For a big red hybrid, Beefmaster set fruit here in Texas all summer long. Maybe the worst of the heat temporarily shut it down, but it would bounce back once things cooled just a touch. Beefmaster was better at setting fruit and fighting disease than Big Beef in the heat. Kellogg’s Breakfast was actually pretty good in the heat and that was surprising. I saved seed from that one and I am growing out those seeds again this season just to see if perhaps I got a lucky heat tolerant Kellogg’s Breakfast.

I've only grown it once, last season, but Oaxacan Jewel was one of the best tomatoes I've ever grown, and I will grow more of them, this season. It was the earliest large tomato to ripen - 7-3 - even beating many of my cherries. Last season was the second hottest summer on record here, and they kept growing all summer. Only drawback was that it stopped producing earlier than others, sometime in September.
Here are some of the photos:

I’ve found Daniel Burson to be pretty tolerant plus most Cherries.

For Florida, I would say that you might be looking for both heat and humidity tolerant. There are likely several members, here, who actually have experience with weather like yours.

For possible varieties, all from reading, not experiencing...

Abu Rawan
Anahu
Annie's Singapore
Arkansas Traveler (several say the best flavored of heat tolerant varieties)
Creole
Creole Original
Enduro
Everglades
Gapan Native (one says the worst flavored of heat tolerant varieties, and maybe all varieties)
Healani
Homestead
Homestead 24 (I heard this is more heat tolerant than the above)
Komohana
Peron
PI 129129
Porter
Sioux
St Pierre
Super Sioux
Thai Pink Egg
Togorific

There are likely many more varieties that growers have had good success with.

One with a vague history is Florida Pink. Someday, maybe I'll get around to trying it.

And, if a Florida grower says pass on any of the above varieties, I would trust them more than the unknown sources for some of my list.

I was recently reading about the tomato Siccagno di Valledolmo. It is a paste that is grown without irrigation. Not sure if that translates to heat tolerance though. Just thought it was interesting.

The only one I heard of was the Arkansas Traveler
Thanks for the in put folks-

@rusty
What part of the world are you in? And what's your elevation? I might suggest checking for varieties that do well regionally (more so than general heat-tolerant varieties). There are different kinds of heat where different kinds of tomatoes prosper and struggle. There are also other factors that affect heat-tolerance, such as soil composition, disease, etc.

Thessaloniki is one that is heat-tolerant in multiple kinds of climates. (I don't know about every kind of climate.) I think it produces more and larger fruits with more water, but the flavor is more concentrated, and it gets more juicy with less water.

I suggest that you initially use AT as a benchmark against other varieties that you choose. And keep using it for several years, as you cannot expect your weather to be the same every year. For your weather conditions, keeping detailed notes would likely help you succeed.

Where I live, I don't care. The weather is too variable to predict success and failure in terms of production and flavor from year to year. It's a crap shoot, other than the known potential of certain varieties.

Guess it depends where you're located.

I started the tomato rocket from the dollar store.
Marion type tomato in a rolled up fiber growing mat.
Unlike the picture on the box,I rolled out the mat in a planting tray to germinate.

Heirloom. Developed by the USDA vegetable station in Charleston, South Carolina in 1960, Marion is open-pollinated and well adapted to the South. A Rutgers type, but earlier and more disease-resistant. Indeterminate vines bear smooth, deep-globed, and crack resistant

Are you looking for open pollinated types only or are hybrids also in the picture?

Why is a description of the flavor left out?

Asking for a friend.

never tasted it but a quote off the net.

That old-fashioned tomato flavor you want in your home-grown tomatoes. And to top it off, though the fruit is tender and juicy, it is a firmer tomato than most.

Rusty it would help all us to answer your questions if you put your location directly into your profile. Then people will know a bit about your growing conditions before they answer you.

OK

@rusty Here's a link to some humidity/heat resistant varieties sold by Ellie, at Bunny Hop. She grows a lot of these right there in Florida, so maybe you can find something useful for you.

Yeah--Ellie is great

I live in SE GA. I have found that heat tolerant varieties isn't as important as growing during best part of the growing season in your area. It's tough to grow any tomato in the heart of summer with 110F heat index every day with rain. Tough to keep the plants healthy, let alone good tasting tomatoes. I only grow a couple of "heat tolerant" varieties. Other than that, just grow what I want until summer. Eight plants gets us more tomatoes by late June than we can handle.
