Northern Territory in December 2014:A cool, wet end to a hot, dry month

The average temperature for the Northern Territory in December 2014 was 30.8 °C, which is 0.4 °C above the long-term average. Daily maximum temperatures were higher than normal for most of the month, but cooler than normal at the end of the month; average overall. A large part of the Territory, including the Top End, experienced a run of very high minimum temperatures during the second and third week. Darwin Airport tied its previous daily minimum temperature record on the 17th when the overnight low was 29.7 °C. The areal average minimum temperature for the NT was 24.9 °C, the highest since 2005. Toward the end of the month a mid-latitude trough pushed northward across most of the Territory bringing over 100 mm of rainfall to some locations. The trough did not extend to the north coast and a classic monsoon pattern did not set up during the month.

  • Warmer than normal minimum temperatures
  • Overall, near average maximum temperatures
  • Wet across most of the NT, no monsoon for the north coast

Notes

A Monthly Climate Summary is prepared to list 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, usually published in the fourth week of the month.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 8 am on Tuesday 6 January 2015. 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.
