Amazed you didn't get more than that looking at the radar! 19mm not that far
to your North. Missed the second wave though.

2.3mm !!!
That's barely drizzle :-)

But I guess it is all relative.

He he you're having Dartmoor weather Alan! You can send it back here if you like
because I'm beginning to miss it now and the skin between my toes is flaking
away :-)

Very dry here with just 34 mm so far this month.

Yes, I was surprised too. But the rain was indeed very light and barely
got me wet on the 30-minute walk to work. I was surprised that I
measured so much!

It certainly had people running for their brollies! Comments along the
lines of "what is this wet stuff falling from the sky" were also fairly
common :-)

Pathetic, 41mm here for September. ;-)

Dave, on the wettest day since August 2005.

I always thought Canterbury and the extreme SE got clobbered by
showers running along the Channel and clipping Kent. How do you
normally compare with Dover 'down the road'?

Not even so far away as Dover, but in Boughton (about 6 miles away as
the crow flies) there seems to be a lot more rain than here. I have
remarked before about how so many heavy storms seem to pass just to the
west of here - on several occasions it's been bone dry here but a walk
of a mile or so into town often shows signs of heavy rain. The same
seems to apply to the far south-east of Kent - a number of times I have
seen radar images which show moderate or heavy rain just around the
coast of Kent (Dover/Folkestone area) but absolutely nothing here.

Perhaps we are just (un)lucky, but I suspect it is more a case of
coincidence. I have checked to make sure that my rain gauge is at least
roughly accurate and I'm fairly sure that my exposure (although not
great) isn't the cause seeing as I've witnessed at first hand the
extreme local differences in rainfall.

4.6mm for the month in Dover, even less fell here today than in Canters
:1.8mm!
The balance will be redressed - Mother Nature pays her debt, be it dry
or wet.

What about the two places over a year? Like everywhere,some summers
you get local TSs that inflate figures - got any long term averages?

Yes- I am absolutely certain that Poole and eastwards to Southampton
gets much more rain of the French export stuff..central to west
Dorset is invariably on the western fringe. Like today actually in
fact!

But of course the long term averages are the key thing and here I am
stuck, as the nearest place to me with records is presumably
Yeovilton. And that is about 20 miles, north west side of the North
Dorset Downs. Do you have any long term averages?

I am about 1.5 miles SW of Bul Barrow (274metres), but I am not at
all sure whether that modest height accentuates rainfall. But of
course, snow falls there in winter quite readily.

Robin, if that puts you a few km SE of Shaftesbury, your 1941-70
mean annual rainfall is 960mm, approx 30% more than Yeovilton's.
If you have more recent averages for Yeovilton then simply apply
a 30% blanket correction which should get you close.

Always bear in mind that AWS rain-gauges typically collect up
to 10% less rain than a standard manual gauge. Sometimes the
difference is even greater. I'd always recommend having a
manual gauge alongside an AWS one.

Making estimates using the 1941-70 rainfall map, Canterbury ranges from
640mm around the northern fringe to 700mm in the southernmost
outskirts. Wye College has 740mm, Folkestone 750mm, Dover
ranges from about 770mm at the harbour to 860mm on the Downs
above the town. 850-900mm is typical of the highest land in the
triangle between Canterbury, Dover and Ashford. The coast around
Herne Bay averages about 570mm.

Philip,

Why is that - is it just a calibration thing ? I often have to amend the AWS
figure after the event with the rain-guage value.

Thank you. I suppose I am actually 20 km SSW. Multimap gives my height
as 140m.
I guess the approx 30% more is the effect of the North Dorset hills.

Ah, I was looking at the wrong hill! Your 41-70 AAR is actually
1070mm which is 45% higher than Yeovilton. There are various
effects at work ... altitude, proximity to the Channel coast, and in
respect of Yeovilton a marked rainshadow in the lee of the various
ranges of hills which almost surround it.

Actually, Phil, probably not calibration at all. I have a top-of-the-
range one at Hampstead, but it still catches 9% less than the manual
gauge. As far as I can gather, the main problems are out-splash (it
doesn't have a raised outer rim) and inefficient tipping of the
tipping-bucket mechanism. Poor design sums it up best, I think.
