Rainfall Stats Sept 2011

[damianslaw]

Be interested to see what the england and wales rainfall totals are so far this month compared to the average. Suspect we are running close to the average already.

Here it has been a wet month so far, with many 'rain days' often delivering 10mms plus and on one or two occasions well above more than an inch. Unfortunately some of our wettest 'rain days' have occured on each of the three saturdays we have had. Yesterday was a very wet day.

Suspect we have a marked NW/SE divide as well, with Wales and SW England also seeing a fair bit more rain than eastern parts.

Stats please...

[Lancashire Lass]

73.5mm so far

Rain days 16

wettest day 6th 12.3mm

[Rainy]

Sept so far 161.7mm. Sept average since 1968 is 134.3mm.

Only one dry day so far this month.

Record wettest Sept was last year with 274.3mm.

Same MO site, same daily gauge throughout.

All the calendar months, other than March, have their record wettest totals since October 2000. The rainfall has increased up here.

It has been a very dry first half of the month here with just 13.6mm to the 18th, which is only 26% of the monthly average.

It continues the very dry period here since February 2010, during which only two months have had above average rainfall and the highest monthly total in that time was last September with 60.8mm.

The annual total here so far is 258.4mm, which is only 68% of average to this point in the year and only 44% of what would be expected annually.

Yes another month which so far has shown a marked West-East split thanks to westerly airstream being in control. The Pennines continue to suck the life out of any fronts moving east.

As do the Welsh hills:

Just half an inch in Coventry and Rugby, another dry month.

Wet here, well over 3 inches to date.

88.7mm here, a lot from localised downpours with 24mm on the 6th and 15mm on Sunday.

[Terminal Moraine]

49.6 mm here so far this month which is 92% of the average at this stage in September. This is still a good deal less than might have been expected with such an 'unsettled' start to the month.

That is exceptionally low. Gordon Manley speculated that, over a period of about 200 years, the lower limit for annual rainfall over cental England would be in the region of 65%. This does allow that localised areas could record even lower values and a case in point is 1921 when most of the area south east of a line from The Wash to south Devon recorded less than 60% of the annual average, and parts of east Kent less than 50%.

[Bobby]

20mm of rain overnight has brought the total for this month to 180mm, average is ~145mm. So pretty wet here.

[Nick L]

13.5mm, we really quite badly need some proper rainfall.

[Andy Bown]

41.5mm to date which is less than anticipated, largely due to most of the heavy showers not affecting Warminster directly.

And today's anticipated Cold Front has remained approximately 75 miles to the W/NW.

[Osbourne One-Nil]

And not very far away, I've received exactly 110mm so far this month. 5 miles away in Appleby though, that drops to just 73mm.

[Teesdale]

115.4mm here

[Osbourne One-Nil]

Damn your eyes.

[Teesdale]

Damn your eyes.

I'm sure you'll over take me before the month's out.

Its only really easterly dominated months that it will be wetter here, they are rare.
