'Below average', hehe. Nowhere in the UK has ever recorded more than 2237 hours of sunshine in a year. Do you know what your record lowest is?
BOM have Sydney data going back to the mid 19th Century on a daily basis, but sunshine data has only been available since 1 Jan 1955.
It has been available from two sites - Observatory Hill and the Airport. More recent data is taken from the Airport site although I've been informed they are "fairly similar".
Combining the two sources into one series of data, and starting at 1955, the lowest sunshine totals were as follows:

I get the impression there is not that much sunshine data available for US sites?
Also would I be right in saying that NYC has a similar, or slightly higher mean annual sunshine total as Sydney? Using my data, Sydney averages 2,511 hours.

That sounds about right, 58% of possible sunshine. I live relatively close to NYC, although based on wavehunter's maps, I think my area is slightly cloudier.
For some reason it is difficult to get sunshine data in the US.
The current (airport since 1976) average stands at 2624 hours. Currently at 2257 hours and the cloudiest since 1999 (2499 hrs) which's about time if you ask me!
