It can be tricky to keep track of Australian weather from the other side of the Earth. It's not only that the seasons are opposite to the Northern Hemisphere, it's also that the weather varies a lot locally, because Australia is a very large country covering several different climatic regions.
Here you have a weather widget, showing you the daily weather in Sydney, Australia. You can enter any place in the little white box under the weather forecast to check the current local weather conditions in different places in Australia.
NOTE: This website is written in British English, which is the English we use in Australia. You will find words like "traveller", "harbour" and "realise", and they are all correct in the language used in Australia.
