Thanks for your comment Dick - as a respected member of uk.sci.weather, I have spent some time looking back just in case there has been s statistical error, which is always possible considering the vagaries of data enties into Excel.

However I have checked our records, and spring 1967 did it seems have an average of 6.9C in Coventry compared to 7.0C in 2013.

I even went back to 1967 files for individual months and found

1967 March ave *4.5C *2013 2.5C
1967 April ave *7.0C *2013 7.7C
1967 May ave * *9.1C *2013 10.9C

Of the other springs that you mention

1968 = 7.6C
1975 = 7.6C
1979 = 7.8C
1984 = 7.7C

The coldest Springs in our records are

1962 * * * *= 6.6C
1941 * * * *= 6.7C
1951 & 1967 = 6.9C
2013 * * * *= 7.0C
1969 * * * *= 7.1C

Not sure that I can explain any unexpected variations with the CET records comparison.

Looking at the figures you give for 1967, Steve, that March mean of
only 4.5C looks suspiciously low when viewed alongside the equivalent
7.0C from the CET.
This particular March was a warm one in central England with an
anomaly of +1.1C wrt the 1931-60 reference period, so the question
arises as to how Coventry could have a managed an apparently much
colder March than normal; by my estimate of Bablake figures about 1.5C
below normal. The Lamb daily catalogue certainly doesn't suggest a
cold month, with no easterlies, and only 4 northerly days. The most
likely explanation is the wrong figure has somehow got into the
records
I am genuinely not looking for extra work for you, but do think it
would be worth checking it out if you still have access to the daily
figures for that month.
