Northern Territory in July 2016: Continuing warm weather; wetter than normal

Daytime temperatures were above average in the north during July, while overnight temperatures were above average in most parts of the Northern Territory. Rainfall was also above average at most locations, particularly in the northern half of the NT.

Generally warm temperatures

  • Daytime temperatures were above average over the northern half of the Territory, particularly in Arnhem Land. Territory-wide, the monthly mean maximum temperature was 0.76 °C above average
  • Above average overnight temperatures across the Territory, particularly in the south; the mean monthly minimum temperature was 1.37 °C above average

Cool spell hits mid-month

  • Thick cloud and widespread rainfall over much of the central and northern NT between the 13th and 15th saw some locations, including Tennant Creek and Gove Airport, record their coldest July day on record
  • Sustained cool weather across the NT for several days following the rain event. Alice Springs experienced its first sub-zero temperatures of the year, dipping below zero from the 14th to the 17th
  • The Top End was not immune to the cooler weather; Darwin's minimum temperature was 13.8°C on the 18th, its lowest July temperature in eight years
  • The warm days returned late in the month: Oenpelli reached 36.3 °C on the 24th

Unseasonable rainfall across central and northern NT

Notes

The Monthly climate summary lists the main features of the weather in Northern Territory using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 10 am on Monday 1 August 2016. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages for individual sites are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.

The ACORN-SAT dataset is used for temperature area averages.
