The Northern Territory is so large it covers two very distinct climate zones: The Red Centre and the Tropical Top End.

Central Australia (Red Centre)
Central Australia, which includes Alice Springs, Tennant Creek, the Barkly Tablelands and Uluru/Kata-Tjuta regions, has a semi-arid climate. It experiences Australia's four typical seasons: summer, autumn, winter and spring. The Red Centre has hot summer days from December to February and surprisingly cold nights from June to August. Spring and autumn are warm throughout the day and cool at night.

 Tropical North
The Top End, which includes Darwin, Katherine, Kakadu and Arnhem Land, has a tropical climate. Darwin has an average temperature of 32 degrees celsius all year, with varying humidity. The tropical summer, from December to March, is considered by many to be the region's most beautiful time of year.

The summer rains bring the natural landscape to life and deliver the picturesque storms and sunsets the Northern Territory is renowned for. The dry season, from May to October, has warm, sunny days and cool nights. At the end of the year, the build up, or pre-monsoon season, begins and humidity levels start their rise.
