Cristobal, it's so frustrating to have trouble with something you really want to grow. Your temperature actually sounds like good tomato weather. As long as the night temps don't go below 50, it shouldn't be to cold. Tomatoes like heat, but not to much. I live in N California where we can see 100 and more in the summer. I didn't realize this until this year ( I should have, it's a kind of a " well duh" moment for me) different varieties do better in different climates. I would do a search for tomatoes that do best in your weather. If you have a farmers market, or local nursery, I would go and talk to the people who are growing tomatoes. Gardeners love to share information. They may have a certain variety that does well, or a planting or growing tip. Unfortunately, or fortunately depending on how you look at it. Growing, well anything, everything is an adventure . Last year my tomatoes sat on the vine a didn't get red for a long time, then they didn't taste good. Then August came and the tomatoes produced, ripened and tasted great. Why??? I will never know. I almost always grow a cherry tomato. They are the dependable work horse of tomatoes. For me they are always dependable. It sounds like you have plenty of pollinators, but if you think this is a factor, you can pollinate them yourself. Some use a little paint brush. I just generally tap on the flowers. I don't do this often, but if there's a open flower near me I will give it a tap, why not? I don't feel this has been very helpful. I wish I had a tried and true way to grow amazing tomatoes every year, but I just don't. I have hugel beets ( beds dug in the ground about 2 feet. Filled with layers of wood and soil) I add organic compost (bought because I suck at making compost) and throw in some organic fertilizers between my crops, like you I can grow year round. I just try to build the best soil I can. Do things like don't till, chop and drop when I can. Grow a lot of veggie, herbs and flowers crammed in, and most of the time it works.
This is already too long, but I have to ask do you stake and prune your zucchini and squash? I have been doing it for a couple of years now and love it. You put a stake in next to your zucchini. As it produces you remove all the leaves under the zucchini, and attach the stem to the stake. This was it grows like a tree. It's easier to find the zucchini/squash. Less disease and fungal problems, because you have more air flow. Doesn't take up as much space, and as it gets taller you can then plant under them. This has been a game changer for me.
Good luck to you, I hope you crack the tomato code in your area.
