The Met Office tweeted this yesterday:
The BBC quickly jumped on the warmist good news and put out this article with the headline:
UK weather: May 2018 hottest since records began in UK
Read the small print though. They’re talking about the daily average maximum temperature. This is virtually meaningless. We need to know the daily average minimum to calculate the daily average mean for the month, which is a far more representative metric for assessing how warm May was. As it turns out, the average Min and Mean figures are not nearly as impressive:
I doubt that a mean of 11.9C (anomaly = 1.5C) and a minimum of 6.9C (anomaly = 0.9C) makes May 2018 the “hottest since records began” [in 1910, by the way]. More warmist Fake News. The most we can say is that the weather in May was highly variable, geographically and temporally.
Paul Homewood has posted about this too. He points out that the mean CET for May is 13.2C. This is warm (equally as warm as 2017), but many May months since 1659 have been warmer – 17 to be precise, stretching as far back as 1726. 1833 was truly the ‘warmest May ever’ at 15.1C, nearly 2 degrees warmer than 2018 and occurring just 3 years after the very chilly Dalton Minimum! Finally, just to keep things in perspective, the 15th coldest May in the entire CET series which runs from 1659 was 1996, illustrating just how variable British seasonal weather really is.
