Northern Territory in June 2017: Dry. Warm days; cool nights in the south

Only a handful of sites in the Northern Territory recorded any rain during June. Maximum temperatures were generally above average, whilst minimum temperatures were below average everywhere apart from parts of the Top End and the eastern Carpentaria District.

Dry throughout the NT

  • Rainfall in the Territory was confined to the far northeast, the far south and a small patch along the southern Gulf of Carpentaria coast.
  • Territory-wide, rainfall was 87% below the long-term average for June and the lowest since 2010.

Warm days, cool nights

  • Much of the NT experienced warmer than normal maximum temperatures during the month, particularly over the southern half; across the NT the mean daily maximum temperature was 0.71 °C above average.
  • Minimum tempertaures were generaly below average, and only some near-coastal parts in the northern half of the Territory saw above average nighttime temperatures. Overall, the mean daily minimum temperature was 0.86 °C below average.
  • Dry conditions and clear skies due to higher than average mean sea level pressure across much of Australia during the month contributed to the cool nights south of NT's Top End; it is likely that this high pressure was also a significant factor in the low rainfall observed over central Australia.
  • The June mean sea level pressure measured at 9 am at Alice Springs Airport was the highest on record, at more than 3 hPa above the long-term June average.

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 9 am on Monday 3 July 2017. 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.
