Rainfall Statistics, 2012

[Norrance]

North west of Arran

Jan 221.7mm (highest recorded for Jan since I started recording in 2004)

Feb 134.9mm (highest for Feb)

Mar 68.6mm (lowest for Mar- but only by 2.5mm)

Year to date 424.7mm.

Very wet start to the year following on from the wettest winter for over half a century, according to local records. Drier March has allowed some drying out to happen in fields etc.

Compare with me here in East Central Scotland:

Jan 22 mms. One third of average.

Feb 10 mms. One quarter of average.

March. 1 mm One sixtieth of average.

The University site still shows a total of 20 mms for the year so far so even lower than me on the Western edge of the city.

[The PIT]

Still stuck on 138.8 mm here bar a slight hiccup this week no sign of any heavy rain in the offering at the moment.

[Roger J Smith]

In Ireland, the Monthly Summary reports an average of 36 per cent of normal for eleven stations in March. I think that the average since the middle of the month has been closer to 10 per cent.

Rainfall stats for this year so far are as follows:

January 33.9mm

February 7.5mm

March 36.8mm

[Summer Sun]

Rainfall this year;

January 27mm

February 7mm

March 10.1mm

Total there was 44.1mm

[Andy Bown]

Not sure where any meaningful rain is going to come from yet this month.

0.5mm from showery stuff yesterday late pm/eve and just 1 sharp hail shower today so far - nothing other than drizzle on the

radar heading in this direction with the front now decaying and likely to do so even further before finally heading South.

[TonyH]

According the the radar accumulator, over 70mm today in parts the far north Midlands.

We managed 30.6mm since midnight and 36.0mm since the rain started yesterday. Its been the highest rainfall total in a day since 6th September 2008.

Its also more rainfall than February and March combined!

Another 10.2mm of rain today taking the total this April to 48.6mm. Thats 97% of the 1981-2010 average for the entire month and its only the 9th, so its looking like the long spell of drier than average months has come to an end.

The 48.6mm in the first 9 days of April is almost exactly the same as what we got in January, February and March combined (51.2mm). Quite a turnaround!

[Summer Sun]

January, February and March brought a total of 47mm worth of rain

The first 11 days of April have brought 40mm, the April showers have certainly delivered here this year

For those with nw extra, we've added a new rainfall total feature which uses the 1km radar data to create daily, weekly and monthly rainfall maps of the UK

[Evening thunder]

I gather you need more than the radar subscription to access that feature from the radar?

Speaking of the Netweather Extra radar though the weather recently has really shown off the new V6 version with the accurate lightning overlay on from the ATD system, it can be slightly addictive to watch it even with no storms in my area!

[Andy Bown]

How much rainfall have others recorded since the unsettled spell began last Monday (9 April)?

The amounts nationwide will be so very localised and somewhat amazingly I have had just 17.5mm in the 6 days concerned!

Reasons being : the heaviest of the main bands last Monday went North of here (I had 9.5mm, half of some measurements in this region), between Tuesday-Thursday prolonged thundery showers affected places to the N,SW and E while the most here in those 3 days came early Wednesday due to a trough, then yesterday into today we had an hour or so of rain late pm Friday but today, which at first glance seemed set for a good fall of rain, saw the retreating trough give just light drizzly showers after it stalled to the N/NE overnight giving a small area more than the total here for the entire 6 day unsettled spell!!

Jan = 54mm

Feb = 16.5mm

March = 25.5mm

April 20.5mm so far

Total = 107.5mm

[Evening thunder]

Just 11.6mm here so far this month! During the 9th to now we have had just 7.8mm, so far less than you even. We had 5.0mm on the 9th (less than many other places due to rain shadow effect from Dartmoor), 2.6mm on the 10th (the only day that got decent showers at my house), and 0.2mm on the 11th.

There have been heavy downpours very close by these last few days including just a couple miles south of here today which I drove through with the roads starting to flood due to surface water from narrow convective cells that gave 3 claps of thunder about 2-3 miles to my SE. Just a few drops here though that wasn't enough to register.

February and March were dry too - and January below the average of near 100mm. Certainly been a drier start to the year this year than last year, although we've already beaten last April's rainfall total.

We've had:

Jan: 62mm

Feb: 26mm

Mar: 19mm

[Norrance]

Here April has overtaken the total so far for Jan, Feb and March.

Jan 22 mms

Feb 10 mms

March 1 mm

April 36 mms so far.

[Aaron]

22.7mm for April

5.5mm in the last 9 days here

17.2mm of the rain this month fell on the 3rd and 4th, 12.8mm on the 4th

[reef]

63.2mm here so far in April, which is 127% of what would be expected in the entire month. Already its the wettest month since February 2010 and we're not even half way through.

Its also more than Jan-March:

Jan: 20.4mm

Feb: 11.8mm

Mar: 19.0mm

[Terminal Moraine]

68.8 mm so far in April, which is 89% of the average for the whole month and makes it the wettest April since 2008 which recorded 78.5mm.

Only 7.8 mm from showers during the week as all the heavy ones missed here.

The last April to record more than 100mm of rain was 2004 with 122.9mm.

[The PIT]

Rainfall so far this year 191.7 where the average is 249.1mm. If the 2nd half of April repeats the first we'll be up to average for the time of year.

[Andy Bown]

Before today my total was 54.5mm for April and there's been at least half an inch since 07.00 this morning.

That may sound quite low for the equivalent totals for other areas, however on most of the showery days the downpours

have avoided BA12.

[sunny scunny]

89mm of rain now for the month after the earlier heavy showers.

[Aaron]

61.7mm for April, overtaking January as the year's wettest month so far

Edited April 23, 2012 by Aaron

[nimbus20]

49mms so far here this month, and 115mms for the year to date. Not too bad considering the yearly average is about 530mms (21 inches)

[4wd]

112mm here, it would be more if all the snow in week one had been caught.

Previous three months together had 68mm.

April average is 45mm.

We're still about 50mm down on average for the year surprisingly, because Jan and Feb are usually among the wettest months.
