So we head towards May, a month that often promises early summer warmth and optimism. April started very warmly, with the CET peaking at 11.6 on the 8th and still at 11.5c on the 15th, but since has drifted down to 9.5c as of the 27th

So what will May bring?

Headline data
The all-time CET average is 11.24
1991 - 2020 Average           11.91
May changes between all-time and 1991 - 2020 is  0.67c
May has the second most minor change between all-time CET and the 1991 – 2020 average.

It is interesting to see that none of the all-time warmest months have been in the last 170+ years

Hi Justin, Hi - just stickied it for you. 😊

Exceptionally difficult guess this month,  some output wants to continue the cool showery weather but other output showing an early taste of Summer. 

---

11.9c please.

Hi Justin. Hi -. It's a hard one to call this month.
So I'll go for.

11.0C.

Been flat out haven’t even had a chance to look at the models. But I’m going to go with 13.5. That’s been in my head all week. I think it’s going to be a warm one mainly due to warm nights. 

I see predictions coming in quick and fast just haven’t had a chance to look at them. 

good luck all.
