I don't know whether this will be supported statistically but my perception is that this is one of the dullest and wettest Augusts I have had to endure here in the NW of England.
Overcast leaden skies and drizzle as I type.
If you define a "boring" month as one with the smallest difference between the warmest and coolest day of the month as measured by the CET Mean, then this has been the most boring August since 1855 so far. Although as there are another 10 days left to record this month AND the data is still provisional I am being a tad unfair
However, the difference between the warmest and coolest CET Mean so far is only 4.1C (11/8 was 13.9, 17/8 was 18.0) and you have to go back 162 years to find a lower range of 4.0C in August 1855
Glad to report that the Met Office has arisen from slumber although the CET for August up to 21st is still only 15.5C (-0.4C)
