The Northern Territory has two distinctive climate zones. The northern end, including Darwin, has a tropical climate with high humidity and two seasons, the wet (November to April) and dry season (May to October). During the dry season nearly every day is warm and sunny, and afternoon humidity averages around 30%. There is very little rainfall between May and September.
In the coolest months of June and July, the daily minimum temperature may dip as low as 14 °C (57 °F), but very rarely lower, and frost has never been recorded. The wet season is associated with tropical cyclones and monsoon rains. The majority of rainfall occurs between December and March (the southern hemisphere summer), when thunderstorms are common and afternoon relative humidity averages over 70% during the wettest months.
On average more than 1,570 mm (62 in) of rain falls in the north. Rainfall is highest in north west coastal areas, where rainfall averages from 1,800–2,100mm.
The central region is the desert centre of the country, which includes Alice Springs and Ayers Rock, and is semi-arid with little rain usually falling during the hottest months from October to March. Central Australia receives less than 250 mm (9.8 in) of rain per year.
The highest temperature recorded in the territory was 48.3 °C (118.9 °F) at Finke on 1 and 2 January 1960. The lowest temperature was ?7.5 °C (18.5 °F) at Alice Springs on 12 July 1976.
