The current rainfall deficit in Tideswell is quite substantial. As of
yesterday the following are the figures:

30-day running total: 52% of average
60-day running total: 41% of average
90-day running total: 35% of average
120-day running total: 33% of average
180-day running total: 67% of average
365-day running total: 91% of average

I appreciate that seasonal variation has a part to play in these
figures but, on average, the driest months of the year here are April
and September and these months don't come into the 30-day to 120-day
totals
shown above, apart from a few days of April in the 120-day total.

Hi, Norman,
Not as detailed as yours but here goes:-
August so far 115%
This year so far 99%, helped by easterlies off the nearby North Sea in late winter / spring with their snow and rain mix.
Past 12 months 91%, same as you.

It was hoped that the Sunday would have provided Scilly with some decent rainfall, the 1st forecast of really active fronts down here for a while. In the event 3mm fell. Yesterday was dry, breezy with good sunny spells in the afternoon, so by the end of the day you wouldn’t know it had rained rec ntly.

(OT) but we saw a small pod of dolphins off Gugh today, on the way back from St Agnes. Hoping to go kayaking tomorrow off porthcressa, which should be very sheltered from the NW breeze.

I haven't carried out the running totala analysis but my driest months
in St Albans are also Setember and April closely followed by March.
August rainfall is 9% above average based on records starting in 2002.

2018 had a wet first 5 months followed by a very dry June and July,
looking at the the charts September is likely to start dry and remain
that way for some days.

It seems like a good time to join in with this comparison now that the August and summer totals are in. Here are my figures for Molesey, north Surrey. This is a drier area than most of London due to low altitude near The Thames.

Last 3 months 43%

Last 6 months 93% (spring was 155% here)

Calendar year to date 95% of the average to this date

Last 12 months (i.e the hydrological year) 84% 529mm (last autumn was very dry). LTA 627mm based on the last 18 years here (but the 30 year averages should be around 605mm- the early 2000s were wet in these parts).

To put it another way, here are the %s for the last 4 seasons.

Aut '17 56%
Win 17-18 99%
Spr '18 155%
Sum '18 43% - with a grand total of 0.1 in June.

The rainfall deficit here has maybe been less intense this year than elsewhere due to the wet spring but each of the last three years has been below average (and below 600mm).

And here on the SW Devon coast there is no deficit over the last 12 months.

Autumn 2017 269.4mm 94%
Winter 17/18 359.9mm 114%
Spring 2018 319mm 154%
Summer 2018 125.8mm 61%

So 106% for the last 12 months.

The summer deficit and the influx of grockles during the hols has depleted our water storage by a large amount.
In the SW we are now down to a total reservoir storage of 60% from a total of 85% in June.
No sig rain in the forecast but not a 'bath with friends' situation yet.

At least, unlike your relations, you can choose your friends!

Enough rain recently to turn things green again, but not enough to raise river levels.
