With the mild climate in Sydney Australia, winter is not too cold. However nights can get colder, but during the day it is usually fine and warm enough.
June can be rainy, as it is the month with the highest average rainfall. You can still enjoy the outdoors, go to barbeques in the park or stroll on the beach. The braver ones keep surfing all year round.
If you are coming to Sydney in winter, bring an overcoat or a wool jacket. You don't need padded clothes. And you don't need boots, unless you want to make a fashion statement.
June, the first winter month, has daily average maximum temperatures of 17 degrees C (62oF) and minimums of 9 degrees C (48oF).
To keep the winter spirit and bring some excitement to shopping, Australians like to celebrate Christmas in July. As it is the coldest month of the year with daily average maximum temperatures of 16 and minimum of just 8 degrees C (61 to 46oF), this is the time for a traditional Christmas dinner with a nice roast and a pudding.
Otherwise the actual Christmas time in December is too hot for this hearty food and Australians stick to oysters, prawns and salads.
With more than 240 sunny days per year, the climate in Sydney Australia will give you something to look for and keep you active and fit all the time.
August, still winter with an average maximum of 18 degrees C and minimum of 9 (64 to 48oF), is a good month to keep warm by... running.
