            Is this a normal amount of UV? Here is a link to monthly averages, and the image below is the UV alert forecast. If you are in the white, UV levels are "normal" for this time of year.

UV forecasts at the South Pole can be found here.

If you are interested in 'retrospective' UV data, or UV data from the past, you can find it here. This took me a long time to find!
