I would take mine outside to play with me all the time when I was younger. I would worry more about other animals than your rat. Mine would always come when called and just liked to hang out, but there were always snakes, dogs, cats, and large birds wanting to eat them.
I really don't think it would be any different than closely supervising free range chickens. Just make sure they didn't overheat.
I had a rat once that accidentally got lost outside. I searched all over, called her, nothing!!!
Finally found her a few hours later, after dark, near the coop where I had lost her, in some plastic tarp, basically catatonic. It took her about 2 hours before she would start moving again. You could set her upright, then just push her over and she would stay there with her legs straight out. It was the craziest thing I had ever seen!!!
I think she was absolutely petrified that she had been left outside. This was the middle of summer, too, so she wasn't too cold. She never left my shoulder again when she was outside! LOL!
I wouldn't worry about the breeze, but give her a box (like the ones you bring them home from petshops in) so she can get out of the breeze and/or sun. They are pretty much like we are...if it's too cold/hot/wet/windy for us, then it is for them, too!
