Possible Lowest Cet Since 2000 Years?

[McLoaf]

As this is my first thread, I'm sorry if this is in the wrong forum.

This certainly is NOT going to be a thread about climat change/AGW etc., but more on historical weather (somewhat like Mr Data's posts).

As you all know, you can get access to the CET monthly record with values all the way back to 1659. (Even though the first 60 years generally are rounded to the nearest half/whole-degree °C)

And so, here are the lowest values:

Jan: -3.1, 1795

Feb: -1.9, 1947

Mar: +1.0, 1674

Apr: +4.7, 1701/1837

May: +8.5, 1698

Jun: +11.5, 1675

Jul: +13.4, 1816

Aug: +12.9, 1912

Sep: +10.5, 1674/1675/1694/1807

Oct: +5.3, 1740

Nov: +2.3, 1782

Dec: -0.8, 1890

Is there any month where the accounts (how fragmented, scant and somewhat exaggerated they may be) seem to describe/indicate a month that could've been colder than these months? For example, a May CET under 8 or even 7 degrees?

I don't wan't any "hard" numbers (like "it could've 8.5°") but estimations, like: "The description (very late flowering, numerous frosts and even occasional snowfall) indicates a CET for that season lower than than 6°"

One example that I'm especially thinking of is the winter 1607/08.

I've heard on uk.sci.weather that it might have had some months below -4°, possibly even -5°.

Another example that made me curious, even though it's in the opposite direction, is December 2006.

Here in Sweden, the month it was incredibly mild, with means reaching above 7° along the west coast, one place even reaching

7.8°C. (The 1961-90 mean is around 1.0-2.0°C on the west coast)

As a comparison, the previously highest monthly mean is from Dec 1857, with 6.1°.

A monthly mean of 7.5°> in December would be very rare in the CET record (only six recorded December months), let alone in Sweden!! (Here in southern Sweden it would fit mid/late-April more, not December!)

Edit: Whoops... I found the Historical Weather section... C**p... Could somebody please move it there?

In response to this thread I thought it might be fun to look at the warmest CET months...but I can only find the figures going back to 1900. This is what I came up with:

January - 1916 - 7.5

February - 1990 - 7.3

March - 1957 - 9.2

April - 2007 - 11.2

May - 1992 -13.6

June - 1976 - 17.0

July - 2006 -19.7

August - 1995 -19.2

September - 2006 -16.8

October - 2001 - 13.3

November - 1994 - 10.1

December - 1934/74 - 8.1

That would produce an annual CET of a sweltering 12.75! I imagine if we had 12 such months that send the AGW argument into overdrive.

The highest values recorded would give a year of:

January - 1916 - 7.5

February - 1779 - 7.9

March - 1957 - 9.2

April - 2007 - 11.2

May - 1833 -15.1

June - 1846 - 18.2

July - 2006 -19.7

August - 1995 -19.2

September - 2006 -16.8

October - 2001 - 13.3

November - 1994 - 10.1

December - 1934/74 - 8.1

An annual CET of 13.03C. Fortunately its not one we're likely to see in our lifetimes, even if the predicted rises in temperature from AGW happen. For one Im glad, what a boring climate that would be, though I suspect many on here wouldnt mind it apart from the latter part of Autumn and winter!
