Don’t worry they’re fine. This is what happens to Aloe Vera when receiving xtra sun. They turn a not so pretty tan color🙂. I prefer them juicy green.

They do turn that brownish color when outside and getting a lot of sun, but they're probably getting too much water with the rain and you watering them. With regular rain, you don't have to water them at all. Mine do best in full sunlight and little water (maybe once a week waterings if it doesn't rain).

That lush life is far from my liking for Aloe vera - I like this species burned, but there are other species, in fact many, many, many other species, that I like for their juiciness. Here's A. vera in flower, irrigated once a week, in Arizona (March a few years ago). This is about as lush as it ever looks. It is, as you can see, in the shade of a tree that shouldn't have been planted.
