This article talks about values of over 30 once you get up to much higher altitudes in Tibet, and over 15 in winter. Pretty crazy for sure.

Cusco Peru has been known to have UV25 - obviously altitude plays a large part but it's not as high has the one I linked above. Above is actually a snow covered mountain so that might explain why it's much higher than surrounding locations.

When the local ne'er do wells are out playing with their car security jamming equipment, my station can record a UVI of 16 at 2am in December.

Reading's first 7 on the 25th, surprised today only just made it above a 6, it's been a stunning cloud free day. Spent lunchtime glued to a flight tracking app charting the planes coming over mostly from Amsterdam heading to the Eastern seaboard. Small things amuse...

I read that, following a nuclear exchange, the soot ejected into the stratosphere would create super-warming there, destroying the ozone layer. 

UV index values across most of the world would be at/over 35.

Lots of 8s in the MetO forecast but none materialised yet as far as I can see. Chilton has had 5 7s recently (23-26 and 29) but Reading has been stuck in the 6s.

Reading and Weybourne just sneaked a 7 today, with Chilton at 7.3

Camborne probably getting some higher values but not publishing graphs regularly. Disappointing.
