Hot most of the year; the Top End has two seasons, dry and wet, whilst the Red Centre has the usual four: summer, autumn, winter and spring. Coastal and some inland areas can receive heavy monsoon rain from October to March. The best time to visit is June to August.

Lightweight cottons and linens most of the year. Waterproofing is necessary in the northern areas during the rainy season. A warm sweater or jacket is advised for the centre during winter months, as evenings can be freezing.
