Central England Temperature–Seasonal Trends

June 14, 2013

By Paul Homewood


I ran through the latest CET numbers for Spring last week, but thought it might be useful to pitch them alongside the other seasons.










And the 5-Year Running Averages.









Looking at 5-Year averages, winter temperatures show the steepest decline, but all four seasons are trending downwards. None of the seasons, however, are at unusual levels when compared with 20thC temperatures.




All CET data is from here.

    That’s peculier. All the seasons look flat over the 400yrs but the yearly have a +ve trend. Is it my eyes?

    Ah, no. I see it now. They are absolute temps. So the change has been sooooo small that it doesn’t show. he he

      It is difficult to focus in on the annual temperatures, but the 5-year trends are much more visible.

    I’m relatively new to all this compared to most, but looking at those graphs from 1650 to 2010 theres only say 0.5C or less increase in temmps for the 3 1/2 centuries
    Is that correct ?

      That’s about the size of it.

      The overall annual change between 1660 and 2012 was +0.9C.

      Counting from the second half of the 20th century (1951-2012), when the IPCC claims man-made warming began in earnest, then the change is +1.1C. This compares to a global figure of +0.67 over the same period.

        Thanks for reminding me about 1951, David.

        The 5-year running average annual CET in 1951 was 9.8C. At the end of 2012 it was 9.9C. It will probably drop further this year.

    Congratulations for making the Daily Mail, mentioned by David Rose under “Madness of the Met Office Summit meeting to find out why our weather is… normal”

    Climatologists advise that we have seen approximately a 0.7 deg C rise in average Global temperatures since the Industrial Revolution.

    The vertical scale on the graphs above makes them look flat but if you examine them closely they appear consistent with this. They certainly don’t appear to be trending downwards as suggested

    Hi – I hope you don’t mind me using an one of these graphs in a post I’ve made about what I think is the quasi religious nature of the climate change belief system at If it’s a problem, just let me know and I’ll remove it.
