Wrinkled tomato skin

Tomato    None Given

I saved a tomato plant in the neighbourhood and its fruiting wonderfully but for some reason the tomato skin wrinkles when it starts growing a bit , is it the sun? The plant is outdoors and it goes 34C

Saved? From what and how. Contrary to the above answer tomatoes can survive way above 75.2F. I think David looked up ideal conditions - and this would be for average temps probably. Tomatoes can tolerate temps into the 100's - and do here. They drop their blossoms, but fruits are usually OK. I suspect that you stressed the plant in some other way - like transplanting it, or moving it to a much sunnier spot. I also see some yellow and brown leaves and that could indicate a blight. I would pick the tomatoes and let them ripen indoors. Let the plant recover, then produce more. I don't think there is any hope for those tomatoes if you leave them on the vine.

Thanks loki, yes they do tolarate much more and that was well administrated theough my experiance yet i saved it from an abandoned home garden, No i didn't transplant it, rather i took it as is, the spot is a bit sunnier though so i placed it in a more shadower spot.

Tomatoes grow very well in warm areas at temperatures between 21 and 24°C (69.8–75.2°F).

34C is would be too hot. I suspect they are heat stressed

That wrinkling is called "Catfacing." It is caused by a drop in temperature when the tomato plant blooms or begins to set fruit. Like moving the plant from a sunny spot to a shady one. Most catfaced tomatoes are edible, but ugly.
