Winter (June to August) is cool but not cold. Most rain falls as a result of a few off-shore low pressure systems, which usually result in two or three rainy weeks during winter. The Icebergs will be in the ocean doing their morning laps, but most of Sydney will be well away from the beach. It does not snow in Sydney, and unless you intend spending long periods outside, you can usually get by with just a warm top. Sydney is a year-round city, and only the outdoor water-parks close for the winter. If the beach isn't your scene, and you don't like the heat, winter may be your time to visit.
