    I thought it would be interesting if I were to work out every 12 single month in the 15 year span and see what it comes up with. Firstly I've added all the 15 months of the first 15 years of the 20th century and divided the whole number by 15. Here's what it ended up as;

    (I've added the period averages beside them to show you the anomoly of each working out)


    1961-1990 Average; 1971-2000 Average;

    January; 4.1c (+0.3c) (-0.1c)

    February; 4.4c (+0.6c) (+0.2c)

    March; 5.8c (+0.1c) (-0.5c)

    April; 8.3c (+0.3c) (+0.2c)

    May; 11.8c (+0.6c) (+0.5c)

    June; 14.8c (+0.7) (+0.7c)

    July; 16.9c (+0.8c) (+0.4c)

    August; 16.2c (+0.4c) (0.0c)

    September; 13.9c (+0.3c) (+0.2c)

    October; 10.5c (-0.1c) (+0.1c)

    November; 6.3c (-0.2c) (-0.6c)

    December; 5.1c (+0.5c) (0.0c)

    Overall start of the century was a very warm period. Apart from October and November, all the years were above the 1961-1990 mean October and November were a little below. March and November was well below the 1971-2000 mean. Yet all of the other months were close to or well above the 1971-2000 average. June being notably warm on both averages.

    Then added all the average numbers up for that period and divided by 12;

    Yearly averages for 1900-1915

    1971-2000 9.75c (+0.05)

    1961-1990 9.48c (+0.32c)

    I'll also do the same for 1915-1945, 1945-1960, 1960-1975, 1975-1990 and 1990-2005 when I eventually tally up the months, I will add them to the thread. That way we will have a record of how diverse the trends were for the 20th century to present.
