I see from http://www.climate-uk.com that not only are we currently running at over three times normal rainfall for the first third of July, but that as of yesterday we were almost exactly up to the mean rainfall figure for the whole month: today's rain will certainly push it well above. If anyone knows (Kevin?) how to analyse the data, I'd love to know where that puts 2008 in the E&W wetness rankings for the first ten days: I think the daily data started in 1931.

We're also well ahead of last year's wet kick-off to the month: with ground soaked and rivers full, let's hope that we do not have anything like a repeat of the rains of late July 2007 as well.

Does anyone (Kevin?) have data for south-west England? I ask because it has rained cats and dogs pretty much all month here and Wednesday's rainfall was the highest here in the UK; 56 mm on Exmoor and 47 mm just up the road at Chivenor.

Staggeringly wet start to July ...

We're being let off today with only 15mm so far (unlike yesterday pm's shower which put 20mm in over an hour). Over the last 7 days I've emptied over 100mm of rain (more like 4 inches really) which is total dross for July!!! Mr D. should think himself lucky for living down there in the lowlands of Chat Moss :) .

81.6mm here so far, with over half of the month to go. Certainly different to June which only totalled 17.9mm for the whole month!

After the first 10 days of July 1968, it was 72.7mm

Long way to go to beat the July of 1828 with 182.6mm

After a scan of the (not-too-easy-too-read) Hadley daily tables for England & Wales, it looks as if 2008's provisional 57.1mm may put it third in the wettest first ten days league (since 1931 - 78 years), after 1968 and 1988 (which just beats it at 59.19mm). Hmmm....those pesky summers ending in '8' again!?

Nearly half of 1968's 72.7mm deluge happened on just one day, the 10th - in fact the E&W av total that day (32.7mm) was even higher than last year's 20th July. It went on to be a fairly wet month overall, but only just squeezes into the top 50 of wettest July's since 1766 (242 years). July 1988 was more impressive, coming in at number 16.

Richard, Philip's regional data up to 15/7 confirms an obviously miserable month: at 68% of average sunshine (lowest in E.W, NI, RoI), mean temperatures 1.0c below (worst in BI by 0.2c) and a remarkable 337% of average rainfall (by far the worst in the BI).

Yup, that pretty much sums up the SW this month, cold, wet and miserable with the odd hour or two of sunshine; even the odd day or so when we've been really lucky. Not the greatest of summers so far.

We're now above average and if the heavy rain / showers turn up later today and this weekend we maybe trying to beat last years July. Although last July it did rain on 29 days out of 31.

At this stage, I would say unlikely. Last July was the wettest since 1888 for England and Wales with 139.4mm and there is nothing in the rainfall ensembles that suggest anything especially wet over the next few days.

This is the 144hr rainfall total on GFS

Obviously a long way away, and very unlikely to come off, but some very wet scenarios for the end of the month in the south east now being suggested by the GFS:
