Currently just 356mm for the year.

[Flatlander]

Provisional 321.8mm so far here - August was a bit damp, although we have a summer maximum here a lot of the time. Not really an unusual total for our area.

356.4mm for the year so far = 66.8%

[BUTTERFLY]

A total of 578.4 mm to the end of September at my place of work here, with 27.2 mm since (24.6 mm on 1st and 2.6 mm on 3rd October) giving a total for the year to 3rd October of 605.6 mm; I think the total in my garden this year has been somewhat higher. These figures are probably not too far from normal. Although the gauge at my place of work is more exposed than the one in my sheltered suburban garden (about a mile and a half away in a direct line) in recent years the garden has often had slightly higher rainfall, including the extremely wet month of August 2008 which has 200.4 mm in my garden but a fair bit less (around 160 or 170 mm I think, from memory) at my place of work.

350.5 mm = 76% to 30th September.

Well Thames Water will be glad it hasn't been a roasting summer. August did bring a little restbite to the drought around here, everyone was saying it was raining all the time but it was just average. September brought barely 10mm. So year to date is 267mm (excluding any <1mm days), I don't have any longterm data but I'd say things are around 60% of average around here. Today I noticed the grass starting to brown and the local playing field is completely burnt off, the river in Abingdon is the lowest I've seen it in 10 years. Unless the Autumn turns very wet this is going down as an exceptionally dry year...

[Ian Williams]

667.0 mm to the end of September, the normal amount til then is 668.1 mm so just 1.1 mm short of average after 9 months or 99.8% of average.

The graph shows 2005 the driest year i have had and 2008 the wettest, for comparisons with this year and the mean average for nearby Plymouth 1971-1990

A few miles makes lots of difference. Huntsham rainfall has been average over recent months but because of dryness earleier in the year, a deficit still exists. Current year rainfall is 573.6mm which is 79.5% of the long term average (721.4mm)

Edit: The 'rolling Rainfall' shows better the present dryness compared to the long term trends.

272.9mm to the end of Sept which is 60% of average (based on MetO 71-00 data for Stratford)

Nothing so far in Oct.

Oddly, and this is part of the Dartmoor rain shadow dryness this year, only 535mm here - and I suspect we're just within the in the 1200mm isohyet. There are place around Exeter and Newton Abbot much below that (an AWS in Kingsteignton showing 371mm for example).

Indeed, this year is, I think, remarkable for it's rainfall variability - perhaps due to it's lack of westerliness and of rain bearing depressions sweeping across the country.

Edit: that rolling figure of yours in interesting. We were only saying today it's still potentially '76ish' around here.

I tend to agree about the dryness. I for one will be hoping for a wet Autumn and Winter. It would be interesting to compare that plot with some other parameters such as westerliness, +ve or -ve NAO etc!

378.9mm here so far this year - 94% of ave.
January (93.7mm) and June (97.6mm) had about twice the normal, but March (10.9mm), April (3.7mm), May (11.4mm) and Sept (13.4mm) were all very dry.

[BUTTERFLY]

http://www.ceh.ac.uk...f/HS_201108.pdf gives a summary for the rainfall in August 2011. It mentions that only 12 mm was recorded at Shrewsbury, but that Northern Scotland, except for the islands, was very wet. The Midlands (I think his refers to River catchhments and probably doesn't tally with Met Office regions) had the lowest actual and % rainfall (45 mm or 72%) while Tay had the highest rainfall at 176 mm, though its percentage (212%) was exceeded by NE Scotland at 244%, though the latter had only the 2nd highest rainfall at 170 mm. (Tweed with 232% and Forth 2030% also exceeded twice the average). For June to August, rainfall varied from 144 mm in the Midlands to 420 mm in the Tay area, and percentages from 82% in the Midlands to 186% in the Tay area.

For March to August 2011, Scotland recorded its 2nd wettest ever such period (the wettest being in 2009) but that England and Wales only recorded 80% of average. For the midlands, the combined spring and summer rainfall was the 2nd lowest on record, and the deficiency in the 21 months (from December 2009 to August 2011) was exceeded only by the extreme droughts of 1933/1934 and 1975/1976.

http://www.ceh.ac.uk...f/HS_201105.pdf shows similar figures for May and spring 2011, showing that Scotland, with 190 mm (260%) had its wettest May on record, but that England and Wales had its joint driest spring, along with 1990, and that the Cambridge area had its driest spring on record, half the amount of the previous lowest, in a record going back to 1848. Southern (41%) and Anglian region (45%) both only averaged 21 mm in May 2011, while Highland regon averaged 252 mm (322% of average). For spring as a whole, Anglian averaged 31 mm (23%), and Southern averaged 43 mm (27%, both these having a frequency of 1 in more than 100 years and Highland 486 mm (146%), a frequency of about 1 in 30 to 40 years.

Someone mentioned a link to an an on-line article by Philip Eden in a thread on UK Weatherworld recently, in which he mentioned a low rainfall total somewhere in England in September 2011; I cant remember the amount or place and unfortunately cant find the post easily in which it was mentioned, though think it was in the last 2 or 3 days. I have tried searching for posts mentioning Philip Eden in the last few days and it returns about 11, but it is tedious to search these one by one. Under the old UK Weatherworld website, you could show only the posts which showed the actual words you were looking for; is there any equivalent of it under the new set-up (Computers are supposed to cut down on boring but necessary tasks)?

Click on advanced (to the right of the search box) - that should help

Cranwell, Lincs, 9mm

[Norfolkweather]

Up to 5 Oct just 244.4mm (54% of YTD average)

which makes it the 3rd driest YTD since 1900

[00ctober]

January............63.2mm (66%)
February.......171.3mm (248%)
March...............22.5mm (27%)
April.................31.8mm (55%)
May................74.8mm (134%)
June.................67.3mm (87%)
July................96.2mm (135%)
August..........118.6mm (133%)
September.....141.7mm (152%)

Year after 9 months - 787.4mm (114%)

http://www.climate-u...onthly/1109.htm, although it wasn't the original online article where I read about the low rainfall total at Cranwell (9 mm) in September 2011, does in fact give more detail; among interestinf facts and statisics shown on the page are:

(1) Cranwell recorded 9 mm and Moulton Park in Northamptonshire 11 mm, while Cluaine Inn in Wester Ross reached 533 mm (including 56 mm on 21st) and Tyndrum in Sirlingshire 414 mm; percentages of monthly rainfall varied from below 30% in the Midlands, East Angia and Kent to around 200% in the Western Highlands of Scotland. Capel Curig recorded 111 mm in the 48 hours ending 2100 hours on 6th, so is extremely likely to have recorded more than 56 mm in 24 hours; Tyndrum also recorded 131 mm and Cluanie Inn 88 mm in the 48 hours ending 0900 hours on 13th. There were only 3 days with 0.1 mm or less at Stornoway in the Hedbrides compared with 21 such days at Wittering in Cambrideshire.

(2) Perhaps surprisingly, the highest minimum was not in the SE during the last week, but 18.0 deg. C. at Crosby on Merseyside on 10th.

(3) Sunshine varied from 41 hours at Kinlochewe in Wester Ross and 72 hours at Eskdalemuir in Dumfries & Galloway to 180 hours at Jersey Airport and 181 hours at Manston in Kent, and percentages from below 80% in Western Scotland, Northern Ireland, and North Wales to around 120% in Eastern England.

It is interesting that the wettest ever September recorded at one of the stations in the table (Wattisham) was 119 mm in 1968, and that it was followed by the driest, 1969, with only 1 mm. Reminiscent of August 2003 and 2004, when Kilkenny in SE Ireland recorded 1.1 mm (see http://www.met.ie/cl...etins/aug03.pdf) and over 100 times that amount in August 2004 (128.4 mm - see http://www.met.ie/cl...etins/aug04.pdf). However as one station in Co. Laois recorded no rainfall in August 2003, the ratio of rainfall in August 2004 to that of August 2003 must have been, by definition, infinite. (This woulso also have happened with respect to August 1801, 1947, 1976 and 1995, all of which were rainless at at least 1 site in Ireland, and were followed by normal to wettish Augusts at least in the last 3 cases (I have no information n August in 1802).
