What is the lowest UV rating you can get a tan from?

Question

Today, the UV rating in my area is 6 (high). Would today be a good day to lay out for an hour or two to tan? Or would I be wasting my time?

Answer 1

You can get a tan from any uv index, but it takes a high uv index to get a fast tan. If its 6, then that's not bad. It will probably take a while though.
