Looking at the Sydney observations, it seems July last year had more sun than December. That is strange at 34S. Also, an E or SE wind seems to be the norm in summer (when it often brings cloud), while W or NW seems much commoner in winter. If that's the case every year, it ought to have a marked winter dry season.

July was just sunnier than December by 30 hours. That is not a dramatic difference in my book. Not to mention, it really depends on the year - In one year July is extremely cloudy and in the other it's the sunniest month of the season. Sydney isn't very predictable.
If you were too look at our monthly sunshine stats you'd see that May and June are the darkest months (late autumn/early winter), NOT summer.
Why did you point out the latitude, as if that's a crucial influence? You're forgetting about our climatic zone and location - A lot of Cfa places do get a cloudier summer. Don't forget, Sydney's on the east coast, it will not be like Perth or Los Angeles.
Despite getting more cloudy days in the summer, June (winter) is the month that gets the most rain. Although in the western suburbs, Feb-March get the maximum rainfall. So saying that Sydney has a "marked winter dry season" is plain erroneous and misleading.

I have quoted Sydney's average % values before - highest around August, lowest in January. And the re is much less rainfall on average in the second half of the year, than in the first half. The following are monthly and annual % values of the astronomically possible sunshine (not necessarily all measurable) for Sydney Airport.

I said it *ought* to, given the apparent change in prevailing wind direction... As for the latitude, 34S is well outside the tropics, meaning the day length is significantly longer in summer than winter. So you'd expect summer months to always be sunnier in terms of total hours, unless it had an extreme Cwa/Cwb climate like parts of China.

They are sunnier in terms of total hours in Sydney if you consider the "sun seasons" - Nov-Jan, Feb-Apr, May-Jul, Aug-Oct - except that the "spring" season gets the most hours thanks to higher percentages, as shown in my table above. The totals for these 4 seasons are about 706, 624, 573 and 762. Your "ought to" regarding rainfall is somewhat satisfied by the fact that the second half of the year is considerably drier than the first half - as was already noted.
