Northern Territory in June 2020: Warm days and low rainfall

Daytime and overnight temperatures were above average across much of the Northern Territory in June. Rainfall was generally below average, with most rainfall confined to the northeastern Top End during the month.

Temperatures mostly above average, particularly in the north

  • Territory-wide, the mean monthly maximum temperature was 1.3 °C above the long-term average. All parts of the NT had average or above average maximum temperatures, with the largest anomalies observed across the Top End and Carpentaria District
  • Nearly all of the Top End and Carpentaria District had a mean monthly maximum temperature in the highest 10% of records; for the Top End (based on the area north of 15 °South), the mean maximum temperature in June 2020 was the fourth-highest on record
  • Daily temperatures were well above average during the middle of June, with Darwin Airport having its highest June temperature on record on the 15th, with a maximum of 35.0 °C
  • The mean minimum temperature in June was 0.39 °C above the long-term average for the NT. Much of the southern third of the Territory had a below average mean night-time temperature in June, but elsewhere it was mostly above the long-term average
  • For the year to date, the NT had a mean maximum temperature just over a degree above average and a mean minimum temperature just below a degree above average: The year-to-date mean temperature of just over a degree above average is the 10th-highest for any January to June period on record for the NT

Below average rainfall

  • Rainfall was confined to the northeastern Top End and the Darwin area during June; no rainfall was recorded elsewhere across the Northern Territory
  • Averaged across the NT, rainfall in June was 98% below the long-term average, the lowest since 2006 and 10th-lowest June total on record. While rainfall totals are generally low in the month of June across the Northern Territory, parts of the southern NT have average rainfall up to 25 mm
  • From 1 January to 30 June, rainfall across the Territory this year has been just below the long-term average. However, parts of the southern NT and the Top End had well below average rainfall in the first 6 months of 2020
  • Related to the relatively dry conditions in the north, the official start of Northern Territory Fire Danger Period (based on the presence of fuel and seasonal conditions conducive to bushfire outbreaks) commenced on 26 June, slightly earlier than the regular 1 July date. During June, Bushfires NT reported many wildfires, a number of which caused significant damage to property

Notes

The Monthly climate summary, generally published on the first working day of each month, 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. More extensive discussion of significant weather events, along with later information and data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

This statement has been prepared based on information available at 1 pm on Wednesday 1 July 2020. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

In some situations, some or all of the rainfall is in the form of hail or snow. In these cases the totals given are for the water equivalent: the depth of liquid water that results from melting any frozen precipitation. There can be significant 'undercatch' of snow in strong winds, meaning the true precipitation can be higher than that reported.

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.

Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
