Here are some interesting "facts" about sydney weather:
- Sydney has almost the same number of wet days per year as London UK
(152 wet days for sydney, 153 for london. a wet day has 0.25mm rain or more)
- Sydney is the "wettest" city i have ever lived in
(i have lived in athens-greece, princeton-NJ, toronto and sydney)
- Sydney has only 100 sunny days per year. Las vegas has over 200.
(ok my stats for sydney and las vegas are from different sources using different definitions for sunny-ness: sunny day for sydney has average cloud cover less than 25%, for las vegas it is up to 1/3 cloud cover.)
- In april 2008 we had 12 continuous days of rain in sydney. plus some more (non-continuous) days of rain. feb-march were just as bad.
For me the definition of good weather is simple: sun. Temperature is not very important, as long as you have sun. Having lots of sun implies that you cannot have terribly wet weather, you cannot have tropical weather etc.
The definition and most statistics for wets days comes from BBC.co.uk/weather website. For example here are some links, for the averages for sydney and here for toronto. Or you can look up other cities starting here. The source for the number of sunny days in sydney is the Australian Bureau of Meteorology.
