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 areas have heavy monsoon rain from March to November.

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 quite cool.
