One does wonder if there is some pattern emerging, I put a comment in
with my COL annual report noting a decrease in southwesterly winds in
2010. The year has bucked the trend and turned out -ve to the
1971-2000 average, yet July was 2°C above the average. The highest
increases in your figure appear in the Spring and Autumn months, yet
January is only +0.2°C. Could this be a sign of colder winters and
hotter summers ?

It does seem apparent to me that our weather patterns and maybe
climate, is going into a different phase!

I am seeing something quite similar. Every decade, I compare (using
CET) the 30 year and 10 year everages. This gives an idea how average
temperatures of the last decade compare with those of the last 30
years, and could be an early indication of trends.

Comparing 2001-2010 with 1981-2010 gives the following for each month:

January +0.37C
February +0.91C
March +0.58C
April +0.49c
May +0.29C
June +0.22C
July +0.37C
August +0.79C
Sepetember +0.38C
October +0.38C
November +0.78C
December -0.20C

You will notive that December is the only month that appears to be
getting cooler. All of the others are warming.

Clearly one very cold December will have more of an effect on the
2001-2010 mean than it will on the mean for a period three times as
long. If one argued that December 2010 was just one freak month, and so
compared the December means for 1981-2009 with 2001-2009, would there
still be a cooling trend?

If we assume that the anomaly for Dec 2010 was -5°C the effect of
this will be to lower the 2001-2010 mean anomaly by 0.5 degC, a large
amount. This entirely removes the negative relative anomaly for
December 2001-2010 compared with 1981-2010, though the positive
anomaly that would result is less than that for most other months. So
I think is it is fair to say that December has got colder recently,
relative to what one might expect. This sort of variation is not
uncommon. Often a month, or sometimes two, is colder or warmer than
usual for a few years, maybe a decade, then reverts to normal. The
same thing is seen, probably more markedly, with rainfall.
