Highest UV since August on Wednesday – but very cool again

Wednesday was another very cool day thanks to the persistent northeasterly wind gusting 25mph and producing wind chill again. The thermometer briefly rose to 12.1C at 12.48, being a significant 5C below average, but increasing cloud after midday began to limit sunshine that totalled 8.2 hours.

It was another dry day, the eleventh this month. In the midday sunshine the UV level rose to 6.9, which was at the top end of the ‘High’ rating and not seen since 8th August last year.

The thermometer dropped steadily away during the evening and night to reach a low of 0.2C. This was 6.8C below the 36-year average and although not producing an air frost would have given a brief ground frost.

Thursday saw strong sunshine after dawn in a crystal clear sky that lifted the thermometer to 6.6C at 08.00.
