Now that the dust seems to have firmly settled, it's worth reiterating the daily record for the 1st (-3.8C). Not only was it a daily record, but also the fourth coldest March day on record. To put tha

My impression is that a large part of the reset from provisional to final CET is to remove values for max and (more often) min that are outside the boundaries of the 24-hour calendar day and to introd

I suspect the 4.9C figure is not the final figure. The mean using the provisional values is 4.9C, and that's now been removed from the monthly rankings. Possibly posted by accident.

The data aren't there when I click the link.

Edit: Min. and max. data seem to be there. If they're correct then the daily record for the 1st looks to have been broken (-3.8C, previous record was -3.5C in 1785). The March maximum record looks to have been smashed as well (-1.2C, previous record was -0.7C on 6th March 1942).

This is what I see when I load the page - only 2 months of data so far. Looks like the March figures haven't reached Reading yet :)

[Edit - just updated after some determined page refreshing!]

About 3 hours ago there was a March figure of 4.9c, but they have taken this down it would seem. So someone at the Met office is working on Easters day then?!:)

How very strange, the data have disappeared again!

18th March: -1.1C 

I think that's the coldest CET daily mean for the second half of March since 1899.

Yes, very cold; -1.1C puts it in second place for that particular date (18th March 1853 was -1.3C).

My apologies for seeming a little dim :oops: but how do you work out the fig of 4.93c from that chart :)

Yes I'd like to know that too!:rofl:

Ignore what I said previously. Probably just best to wait for the official data, which seem to be appearing and disappearing at random at the minute!

On another note, I still can't see the 4.9C figure in the monthly rankings?

If you take the mean of the minimum and maximum for each date, and then then take the mean of all of those values, then presumably it comes to 4.93C.

Sunny Sheffield finished on 3.7C -2.6C below average. Average max 6.9C -3.0C below normal. Average min 0.5C -2.3C below average. Rainfall 138.3mm 217.1% of average Strange to have such a cold month a wet month as well. 2nd wettest for us on record since 1955

After a quick look, the top 3 largest drops for the CET from one day to the next in March are:

8.5C from the 28th in 1777
8.5C from the 4th in 1821
7.5C from the 25th in 1858

It will be interesting to see how the drop from yesterday to today compares!

8.2C drop

Now that the dust seems to have firmly settled, it's worth reiterating the daily record for the 1st (-3.8C). Not only was it a daily record, but also the fourth coldest March day on record. To put that into some perspective, the coldest day of December 2010 (the 20th, -7.0C) "only" managed to become the eighth coldest December day on record.

It's interesting to compare to last March. Last year we saw the warmest March day ever, the first ever to exceed 15C. A year later and a day in the same month comes along and registers a mean which is 19C lower.

(For those who are interested, the only colder March days were the 3rd in 1965 (-3.9C), the 6th in 1786 (-4.7C), and the 13th in 1845 (-6.5C).)
