By "clear days" I mean when the sky is over 80% cloudless or blue.

Examples (if you want to get the picture):

Sydney: 107
Melbourne: 46 (gee, it is bad as they say it is)
Adelaide: 88
Brisbane: 126
Perth: 144
Los Angeles: 147
Miami: 74
San Francisco: 160
Las Vegas: 210
New York: 98
Seattle: 71
New Orleans: 101
Houston: 90
Portland: 68
Atlanta: 110
Chicago: 84
Madrid: 97
Barcelona: 73
Paris: 51
Vienna: 38
Zagreb: 49

Hmm I think this is a misleading stat, as I would certainly class Barcelona and Madrid as sunny places.. particularly the latter which is virtually clear and sunny every day in mid summer. In this sense I am surprised that New York apparently has more clear days than these two cities.

I think 90 or more days would be appropriate.

Some of the cities above aren't that sunny at all. I believe in terms of sunshine hours, NYC is about as sunny as Sydney (Sydney also has around the same summer hours as Portsmouth). Melbourne has the same summer sunshine hours as Portsmouth. Paris is around the same as Heathrow, London... Though I guess this is just showing people comparisons of how many clear blue sky days there are in each city?.. I think a sunny city has to have at least 120 days of clear blue sunny days, and loads more bright ones and partly sunny days to be considered a sunny city...

Over 60% of possible annually is a sunny climate.

Think it has about 200+ more.

It seems there are few things as overstated as Melbourne's 'gloomy' climate on here - compared to Australian cities sure, but it's fairly average world-wide and certainly not in relation to any UK place.

Annually, Melbourne receives more sunshine hours. But during the summer hours are about the same:
https://en.wikipedia.org/wiki/Melbourne
https://en.wikipedia.org/wiki/Portsmouth

Melbourne:
D: 233
J: 279
F: 235
Tot: 747

Portsmouth:
J: 248
J: 262
A: 241
Tot: 751

In fact, on average Portsmouth receives 4 more summer sunshine hours than Melbourne.
And who says you can't compare UK cities to Australia's, yea most cities are going to be warmer or hotter, sunnier and, well, better in Australia than in the UK, but one can still compare them!

Pointless counting days - count hours of sunshine. Climates with a higher preponderance of sunny but partly cloudy days get "punished" when this crass measure is used. As for Melbourne vs. Portsmouth in their summers, there's the small matter of average daylight length to be considered.
