Another day, another jump north - with an 8 popping up in Aberdeenshire!


Can anyone beat that in terms of northerly 8s?

Just got an alert to say that we could see record UV levels today.

Can anyone explain why this record could be broken?

I get it’s sunny and we have just past the solstice. But I assume we have had similar conditions before.

This is largely down to ozone depletion this last winter. The record strong polar vortex led to the worst ozone hole ever in this hemisphere. This despite the fact stratospheric ozone globally is starting to recover from its decades long decline.

We have a particularly holey bit over us at the moment, plus it’s clear and midsummer.

Pollution down, but levels have been picking up in recent days so I doubt that’s a big contributor. I can see an urban smog line over London this week for the first time in a while.

The Beeb has an article about it all here. Nothing new, but interesting to see in the mainstream media.

9s are gone from the map today, but both Lerwick and Sell Ness in Shetland are offered 7s!

Chilton has managed four 8+ this month, with 8.8 yesterday; Camborne just reached 9 today.

I've never been burnt at the wolf centre though, even in years past, as I use factor 50 sunblock. Luckily it doesn't seem to distract the wolves, it must reek to them!

Quite exceptional for the end of July, 8s forecast up to Oxon and Herts on Thursday, still 8s on Friday. Will we get a first August 8?

Despite yesterday being quite gloomy there was a brief bright spell just after midday and I recorded a figure of 7.3.


Will be interesting to see if an 8+ figure is reached later this week.


I haven't checked all my data for this year but it looks like I have only exceeded a reading of 8 once which was 8.1 on 16 July.

Camborne 8.7 and 8.3 yesterday & today.


Chilton 8.6 both days.


Reading lower yesterday, but 7.7 today.


Last days of VH.

Chilton managed a 7 today, which is very late. First one since 7th, and before that a 7.5 on 6th.


Two weeks from now 6 will be unlikely.

August updates from Chilton:


6.6 on 20th


6.5 on 23rd


6.3 on 25th


6.0 on 28th


Less than 6 since.


Amazing how the UV plummets in August.

Respectable UV from Chilton for the start of Sep; since 2nd:


5.0  4.0  4.2  5.5  5.3  4.5


Camborne managed a 5.8 on 6th.


Reading is far out of line with the other two and has missing data.

Excellent sunshine September in the S as far as UV goes:


Reading & Chilton have not failed to reach 4 since I last reported on 7th, (up to yesterday). Chilton's 6.0 on 9th and 5.1 on 13th are worthy of note. Add: Chilton has had no sub-4 day through the whole of September so far, including today. Must be a first.


Camborne meanwhile has dipped below 4 on 5 days since then and below 3 on 3 days, due to less sunny weather, but managed 6.2 on 8th and an impressive 5.0 on 18th.


Gib still topping 8 on occasion.

Chilton scored 3.9 on 27th Sep and an impressive 3.6 on 7th October- the last 3 in fact. Disappointing lack of 2s since then though. 2s really should be waning over the next week.

2.3 in fact on 19th and only two 2s since; 2.0 on both 23rd and 26th. Running around 1.5 at Chilton of late.
