June 2009 in the Northern Territory

Average day time temperatures were greater than normal across almost the entire Northern Territory. In the Top End, most sites recorded zero rainfall, typical for the dry season month, but isolated showers around coastal areas provided significant falls at several sites. Further south in the Alice Springs district, rainfall was about average for the month. June started off cool in the south but by the end of the month the Victoria and Barkly districts were breaking records with their maximum temperatures.

Rainfall

A cloud band at the end of May persisted into the start of June producing some rainfall in the Alice Springs district. Isolated coastal showers occurred around the 23rd in the Darwin-Daly district. Another cloud band covering southern parts of the Northern Territory produced widespread rainfall across the Alice Springs district on the 26th.

The wettest overall was 23.2 mm at Point Fawcett AWS, followed by 15.2 mm at Warruwi AWS, followed by 7.2 mm at Cape Don AWS.

The wettest single day was 22.6 mm at Point Fawcett AWS on the 9th, followed by 15.2 mm at Warruwi AWS on the 22nd, followed by 7.2 mm at Cape Don AWS on the 23rd.

Maximum temperature

Maximum temperatures in the Alice Springs district were suppressed at the begining of the month, due to a cloud band lingering over from May. However, the only site in the Northern Territory whose average maximum temperature was below its climatological average was Yulara Aero AWS. The warmer then usual days were most pronounced in the Arnhem and Roper-McArthur districts where almost all sites recorded average maximum temperatures of more than one degree higher then normal. Hot northwesterly winds ahead of a cold front at the end of the month produced a string of maximum temperature records around the 30th.

The hottest day was 37.0°C at Kidman Springs on the 30th, followed by 36.1°C at Timber Creek on the 29th, followed by 36.0°C at Bradshaw AWS on the 6th, Ngukurr on the 26th and Kidman Springs on the 29th.
