Many waterfalls are spectacular, but it’s not ideal for sunbathing every day. | | Southern Australia (e.g., Sydney, Melbourne, Perth, Adelaide) | Classic “hot and sunny” summer. Dry heat (especially in Adelaide and Perth), beach weather, and occasional cool changes. | | Tasmania (Hobart) | The mildest summer. Pleasant and warm (20–25°C / 68–77°F), rarely scorching. Perfect for hiking and wine tasting without melting. | The One Exception: “Summer” in the Tropics If you live in or visit the tropical north (Queensland’s far north, the Northern Territory), locals often talk about “the build-up” (November) and “the wet” (December–March).
