Western Australia (WA), the largest state in Australia, boasts a diverse climate that spans thousands of kilometers and a variety of landscapes. With its Mediterranean coastline, tropical north, and arid interior, the question arises: Does Western Australia have 4 seasons? The answer is both yes and no, depending on which part of this vast region you’re exploring. In this article, we’ll break down the seasons in Western Australia, explaining how they vary by region and what makes the weather in this incredible state so unique.
