When you’re in the process of planning a holiday to Australia, there are lots of things to think about. After all, you are going half way around the world. Something you may have overlooked, however, is the weather. Being in the southern hemisphere, the seasons in Australia are the opposite to ours here in the UK, and so while we are in the middle of winter, it will be the summer months in Australia.

What’s more, as Australia is such a large country, it’s likely you’ll experience a variety in climates and temperatures, especially if you are embarking on a complete tour of Australia. Take a look at our guide to the seasons in Australia below and the weather you can expect during your visit to the country.
