Nottingham (Watnall) 104
Leeds (Church Fenton) 100
Glasgow (Bishopton) 72
Belfast (Aldergrove) 63
Edinburgh (Gorgabank) 46

Until the recent warm spell, Leeds was actually above the rest.
Even I'm surprised at the very low Edinburgh value. I expected Glasgow to be well in front of the line given I never saw the sun during my three days there. The sun did appear in Edinburgh on one day and a half. It will be interesting to see the final monthly totals, perhaps some new "low" records will be set.
Invercargill (closest relative to those two cities) has recorded, over the summer months of December, January and February, a "low" of 112 hours during February (1987), January 123 hours in 1970 and December 1987 with 112.
In the case of Dunedin, February 1974 saw just 99 hours being measured.

You didn't get up to Aberdeen then? They are on 39.4 hours up to midday on the 27th with less than 20 predicted for the rest of the month - they are going to see an absolutely surreal final score

The abysmally low sunshine totals in parts of the UK are really fascinating. I doubt we'll see something like this again for a long time.

You would assume so, but July 2007, August 2008 and June 2012 (among other summer months I can't remember off-hand) all saw long-lasting local/national low sun or high rainfall records broken, so although the historic cold records seem out of reach these days because generally we'll always get some warmth somewhere to balance out the cold anomalies, anything is possible in terms of rainfall or low sun levels. (I might not have mentioned it, but the period April-July averaged out nationally has been the wettest in history, breaking a record which stood for 232 years.)

It looks like unless August/September are really sunny here March will be the sunniest month of the year with 182 hours (no idea when/if that's happened before, though April was the sunniest month twice in recent years). The dullest month of this year so far was June.

It might even be the lowest %age total any major city anywhere in the world has ever seen for midsummer - so far we're talking about 3 1/2 weeks averaging nearly 90% overcast. I wonder if the seven consecutive completely sunless days they had earlier in the month is also a national record for this time of year?
If I did the numbers right, London had about 24% sunshine possible.

What's Edinburgh's percentage?

Whoops. I did the London numbers out assuming there were 31 days of the month; July's not over yet. I'll assume the posted numbers were for the first 25 days.

Edinburgh is about 11%
London is about 29%

Which London figure are we talking about? We've just had four days of almost non-stop sun which will skew the figures. Hampstead, as of the end of day 27 (assuming the skies stay overcast until sunset as predicted) is on 117 hours, out of a possible ~410 or so, so you won't be that far out - it sounds about right from somebody who's been living here. 24% is a typical winter sun percentage, so it's only unusual for the time of year.

Aberdeen's 39.4 hours after 26.5 days (or roughly 450 possible hours) comes out at less than 9%. I had a brief look to see how Torshavn's been getting on but couldn't find anything other than this forecast - practically no diurnal range whatsoever, only 1C difference over nearly a week!

The latitude is obviously not comparable and I know it's not inhabited but if Bjornoya (average July precip. = 30mm) can average 79.4 hours for July out of what I imagine to be 744 hours of possible sun or something very close then it must have had some shockers in %age terms (which unfortunately I have been unable to find). What's Campbell's worst summer total?
Those sites are much higher in latitude than Waimate, and I'd question Eskdalemuir on both of those grounds. ... and I'd like to know what Bornoya's "horizon" looks like.

Camppbell's worst summer totals were 46 (Dec), 46 (Jan) and 32 (Feb) - on the optimistic side, the % vales are about 10, 10 and 8.

Worse totals in terms of summer or near-summer months, apart from Waimate's infamous already well-covered 60 (13% poss) in December 1959 include:

Timaru March 1979, 59 (15-16% poss)
Waimate Dec 1937, 82
Timaru Feb 1974, 70
Haast Feb 1966, 70
Timaru Dec 1959, 90
