What was the 2021 Cet?

---

Hadley has 10.26C  https://hadleyserver.metoffice.gov.uk/hadcet/cetml1659on.dat

I think that means I win the annual CET competition as I predicted 10.32C!

You were second with 10.10C.

Here is a reminder of the predictions

Congratulations on your annual prediction 👍🏼
I was looking good after Day 10 in December then it all went a bit mild 😂

Coldest year since 2013 thanks to a cold spring. 

---

 Wow!

---

Congratulations GW!

Here are the charts for December

The minimum CET was over 2C above average although only the 16th warmest on record.

Annual CET competition - year-end update

Firstly congratulations to marting for winning the December competition with an error of just 0.04C.

In the annual table there is no change at the top this month. In the end Spring Sun Winter Dread is a comfortable winner by just over 1C. Saint Snow finishes second and Bolty third.

Grandad props up the table this year with an error of 20.02C.

This table shows all the monthly prediction errors and positions of everyone in the final table. Yellow highlight indicates a prediction error of <0.5C and orange highlight indicates a missed prediction.

Is that right ?

I thought I saw 12.9 when I went into the MetO database

---

Sorry yes I was looking at the wrong figure - it is indeed 12.9C so just short of the record. Still the equal second highest on record I think.

 

Congratulations to SSWD

A well deserved winner.

Many thanks .
I was trying to explain this to a friend while sozzled last night when we were discussing 2021 achievements and the best way I could think of to put it was
"I've won fantasy weather on the internet" (riffing on fantasy football which is essentially the same as this but for the Premier League...)
Many thanks to GW for the always on point analysis and charts and here's to another year of weather watching in the competition that makes weather exciting even when it's "boring"! (Much like Fantasy Football in many ways come to think of it...)

Well done SSWD and GW, its a tough competition and to win is a worthy accomplishment. 

---

  Well said and congratulations!  

---

Congratulations SSWD.  

I probably had the best year I've ever had at this game apart from November and December. 

Great effort as always GW.

 

---

Congratulations to SSWD for his win and Global for the annual prediction win!

By far my worst year ever, at least in terms of position. Onwards and upwards for 2022. 

---

Well done sswd and thanks for the excellently run comp GW, have you got the cummulative table over all the previous years that you have posted before.

Congratulations to SSWD, and many thanks to GW for running this competition.

 

Surprised I moved up a few places in the end despite being more than a degree out for December. 

I was the only person in the competition to fail to come within 0.5C of the actual CET every single month! Some achievement. 

---

Well done SSWD 🙂

---

Cheers, GW

And formal congrats to SSWD

At one point around mid-December it looked like the stars were going to align and the weather gods play ball to bring us that most fabled weather event of Yuletide cold and snow, but twasn't to be and a distinctly unfestive dollop of mild gruel was delivered instead. 

---

  Commiserations Saint!  You had it snatched away right at the end but you gave us a good competition!  Keep it up!  

---

The CET comp can be cruel.

2 years ago I had been leading for much of the year but when it came to December I was suckered in by models predicting a cold spell. It never happened, my rivals for the title predicted much milder and somehow I managed to only finish 4th.

It was a real 'Devon Loch' moment!

---

Saint could have won the overall with a 5.55 or higher prediction in December instead of going low with 4.50.

Bolty and myself could also have won with a high enough prediction but we all went below average.

Nevertheless its a 12 month contest and SSWD was the most consistent player throughout the year.
