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.

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.

A reflection on the second half of the year, from Chilton data.

Last UV 2 26/10 (close to usual)

Last 3 7/10 (close tousual)

Last 4 22/9 (close to usual)

Last 5 13/9 (slightly later than usual)

Last 6 9/9 (later than usual)

Last 7 17/8 (later than usual)

Last 8 5/8 (significantly later than usual)

Last 9 17/7 (unusual)

High 9.3 on 29/6.

I wonder if the lockdown/ partial lockdown arrangements had an effect on UV levels from June to September. Everything seemed to return to normal from mid September.

Delightfully sunny over parts of CS England today; Reading the UV lead with 1.7.

Here the heated car roofs rippled summerishly.

Weybourne snatched a 2 yesterday (Reading and Chilton made 1.9). The jump to 2 in March has shifted over the last few years to February.

I'm trying to make thoughts as to why.

2 reached quite widely now in the S and I expect this to be maintained with the upcoming forecast weather. The usual consistency-with-variation from the key stations but Weybourne's a joke with 5.2.

Sort yer stuff out or stop reporting!

Seems a bit early to me, but TheWeatherOnline is forecasting UVIs of 3 quite widely across the UK tomorrow.

Absolutely dazzling sunshine out there now that the cold, clearer air has arrived, and it's been like that across the midday period, but the stations are failing to reach 3; I see clouds building frequently to the N, W and E, but we appear to be in a brighter pocket with only fleeting showers, these very light. Must be a 3 in this area.

Thanks Roger. That does at least confirm what the stations are showing. I think the warmth of the sun tricked me into thinking the air was clearer. But it's still respectable for mid March- I wonder if there will be a low O3 situation this spring.

Last 2 days, Chilton 3.8, 3.3

Reading 3.8 (so good consistency), no data yet today.
