Are you out of your mind? San Fran averages 3,061 sun hrs. per year. How about Chengdu? That one gets 1073 hrs. Chengdu - Wikipedia, the free encyclopedia
London is cloudy too with 1480 hrs. which is typical for the UK but for major cities it is pretty gloomy. Seattle gets 2,174 hrs. and Portland gets 1967 hrs so they aren't even close to "gloomiest city" status.

Anyone else some suggestions? I'm quite sure there are some cities out there that should be on this list, as the gap in China between Chengdu (2) and Xi'an (3) is quite large...

In italics are places which are major regional centres for their region, but don't make the 500K cutoff for metro population to have them ranked.

1) Chongqing, 1055 hours
2) Chengdu, 1073 hours

*) Derry, 1179 hours
*) Bergen, 1180 hours
3) Glasgow, 1239 hours
*) Tromso, 1265 hours
*) Reykjavik, 1268 hours

4) Belfast, 1313 hours
*) York, 1316 hours
*) Trondheim, 1346 hours

5) Bielsko-Biała, 1377 hours
*) Paderborn, 1387 hours
6) Manchester, 1394 hours
*) Aberdeen, 1409 hours
7) Edinburgh, 1411 hours
*) Cork, 1423 hours
8) Liverpool, 1442 hours
9) Essen, 1459 hours
10) Kraków, 1469 hours



Honourable mentions: (Dunedin, and major capitals and world cities with less than 1700 hours sunshine)

-Dublin; 1477 hours
-Copenhagen; 1539 hours
-Brussels; 1546 hours
-Hamburg; 1560 hours
-Warsaw; 1570 hours
-Dunedin; 1585 hours
-London; 1600 hours
-Gdańsk; 1610 hours
-Xi'an; 1616 hours
-Berlin; 1625 hours
-Paris; 1630 hours
-Amsterdam; 1662 hours

Rubbish to put in SF in there though one needs to subtract the usual 200-300, but Seattle's true value is a lot less than 2174 - we've been through this already.

Dunedin's number in the other list is out of date - correct 30-year mean is 1680, and it has shown something of an upward trend in the last decade.

Could someone explain to me how on earth sunshine hours could be over-calculated. How can you actually do that?

It's due to the use of different sunshine recording equipment. Most countries use the Campbell-Stokes recorder while the US uses the Marvin recorder. This second one seems to overestimate sunshine hours (around 10-15%) when compared to the standard non-US instrument.

Not a city, but i have the data that the Orcadas Islands near Antartica has 478 hours, wich would be the world record.

Not unsurprisingly, the city is too small to qualify as a major city, but it is definitely worth mentioning. I'm sure that if the Ferengi are ever going to conquer Earth, this is where they'll set up base...





Our updated list of now:

*) Torshavn, 884 hours
1) Chongqing, 1055 hours
*) Lerwick, 1066 hours
2) Chengdu, 1073 hours
*) Kirkwall, 1140 hours
3) Guiyang, 1150 hours

4) Leeds-Bradford, 1228 hours

5) Glasgow, 1239 hours
*) Tromso, 1265 hours
*) Reykjavik, 1268 hours

*) Quibdo, 1276 hours
*) Murmansk, 1291 hours
6) Belfast, 1313 hours
*) York, 1316 hours
*) Trondheim, 1346 hours

*) Nuuk, 1369 hours
7) Bielsko-Biała, 1377 hours
*) Paderborn, 1387 hours
8) Manchester, 1394 hours
9) Taipei, 1405 hours
*) Aberdeen, 1409 hours
10) Edinburgh, 1411 hours
I like this description, 'Singapore on steroids' . Yes, there's some pretty atrocious climates on that list. Looking at the stats for Chinese cities, it would seem that the capital Beijing is actually quite sunny by national standards (ignoring air pollution, of course).

The title says world.

I would vote cities such as Detroit (lake-effect stratus), Seattle and Portland if we were just talking about the US, but they're not anywhere near the cloudiest cities in the world.
