I would wait until it's bigger to transplant. Tiny seedlings are very vulnerable to a lot of problems, like heavy rain, wind, fungal infection, insects, birds and even animals stepping on them. It's probably not ready for the direct, blazing sun yet either.
If there's any possibility of any of those things getting to it, it will have a much better chance if you wait until it's 5 or 6in. high and has a much more sturdy stem, and several leaves.
I see you are in Mexico, near Manzanillo, but inland. So is there any chance of cooler weather coming along in a month or two? If it's going to get cooler but not cold, that would be maybe a better time to transplant. Are you much higher altitude by any chance? Wet or dry climate? (my map didn't show whether you are in mountains or desert there)
