The first 12 days of June in Cleadon were dry and very sunny in general, though cooling sea breezes ensured that the maxima weren't particularly high during the first 10 days; as the wind changed to a southerly the 11th and 12th were very warm.
From the 13th onwards the weather was rather cloudy and dry with a fair amount of anticyclonic gloom, though the month ended with a couple of sunny days. It continued rather warm, primarily by night,
It was the warmest June since 2003 at Cleadon. The average minimum was actually 0.1C higher than 2003 (although given inhomogeneities in my records, not statistically significant) but the average maximum was 0.6C lower. The sunshine excess of 1-12 June was largely negated by the mainly cloudy weather thereafter, with an excess of around 10% according to the Met Office sunshine maps. This means that June 2005 was actually sunnier than June 2006, while the last significantly sunnier June occurred as recently as 2003.
Leeds did rather better sunshine wise, with an excess in the 20-30% region.
