As most of Australia’s population centres move from winter to spring, the wet season started this week after a drier than usual dry season in Australia’s tropical north.

The Top End capital Darwin recorded its seventh-lowest dry season rainfall on record.

Rainfall was well below average across the entire Northern Territory, with only 10 per cent of the usual amount, the lowest since 1976.

It was a cooler dry in Darwin than it has been for the last two years, with the first surge of cooler drier air from the south coming quite early in mid-May, Bureau of Meteorology figures showed.

Daytime temperatures were above average during the dry season but were slightly cooler than usual overnight.

The warmest day was 36C and the coolest day was 29.5C with the coldest morning 15.3C.

The Top End had its third highest mean maximum temperature, behind only 2016 and 2017; the mean overnight temperature was near average, with 47 nights below 20C in Darwin (average of 51)

Darwin had 33.2mm of rain – 32.8mm of which came in the last week – compared to an average for the entire dry season of 44.5mm.

Alice Springs had its lowest rainfall in 50 years, recording only 1.2mm of rain, which is just two per cent of the average of 63.2mm for May to September.

There was a record 161 consecutive days with no rainfall recorded.

There were many sites in the NT that received no rainfall for the five months ending September.
