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.

Apart from Camborne's 8.5 on 10th, the readings in the South, despite glorious sunshine, have been surprising if not disappointing. Plenty of 6+ and 7s but the forecast 8s seem to be more frequent than ever. This in different airmasses, including lower RH easterlies which often bring higher values.

Camborne reached a 9 today, Reading back offline again, hopefully they add in the missing data at some point.

Leeds not far away from a 9 today, Camborne over and Chilton leading the way with a 9.5 or 9.6 - is that approaching a UK record?

Looks like 9.6 to me tierra- matches the June 2000 reading at the start of this post.

Well spotted Pictures!

Just checked out 9 for Weymouth too. Must be a few along the south coast.
Worth a watch.

Peak UV season now behind us, and the dreadful July leaves a trail of disappointing readings at Chilton (Reading seems to have given up the ghost).
The 9s didn't materialise and we have to go back to 2nd July for the last 8+ (8.3) with just a few 7s since. Only notable was a 7.4 on 1st August. Might get a late 7 on Wednesday or Thursday but 5s and 6s are probably the best order of the day for the remainder of summer.

Interesting to see GFS ekes out a UV 7 here on Sunday... that's got to be very unusual, 2 months out from the solstice!

Several days of 6s still forecast locally which is maybe not that unusual but good to see- the gourd and squashes frames (apologies gardening thread) will benefit.

No not really. Atmospheric ozone is typically much lower in later summer months allowing for increased amounts of UV. Also a less known fact is we're closer to the sun in mid August then we were in late June.

Some places in the south are forecast a 7 on the MetO site today. That is high for this late in the month.
