In your third figure you have put the May average temperatures instead of spring (MAM) temperatures.

Blast! Now corrected - thanks!

So despite the implied link to CO2 emissions by the Met Office, May temperatures are about the same as they were in the early 1800s? And no journalist can be bothered to check the data to reveal that.

Yep, that's about the size of it. I'll probably follow this through with a statistically rigorous analysis that tracks just 5 long series stations over 125 years just to cross check. That's how few truly historic stations we have.

Do you have the quality ratings for each station? You could investigates how significant the ratings are.

No sir! I'd have to create my own index and the trouble there is one of time.

I’ve pinged the MO a message asking. Maybe we’ll need an FOI request.

Are data available to calculate mean of daily maxima in the Mays? I think you’ve made the case before that using maxima reflects whether temps are getting hotter while excluding the effects of nightly warming that plagues the usual mean temperatures.

Not yet - too many holes for my liking. With luck I'll be able to do this next month. I find it odd that they pass the buck to nightly warming as if CO2 shrinks from its job during the day!
