Northern Territory in August 2014: 4th coolest on record

Several high pressure systems over the Great Australian Bight this month meant a strong south or south easterly wind blowing across the Northern Territory. This cool, continental airmass kept humidity low and temperature mild for most of the month. The mean temperature this month in the NT of 18.2 °C was 2.0 °C below average and ranked as the fourth coolest August on record. Several sites (including Darwin Airport) set new record low temperatures. Alice Springs' mean daily minimum temperature of 2.5 °C was their coolest August since 1994.

Overnight temperatures were low all month at Darwin Airport. The mean daily minimum temperature at the Airport was 17.8 °C, tying the previous record first set in 2002 and once repeated in 2012. Darwin Airport dropped below 20 °C twenty-six times this month, including on the morning of the 23rd when the temperature dropped to 13.0 °C setting a new minimum temperature record.

As is normal for August, there was no significant rainfall over most of the Northern Territory

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 4 pm on Monday 1 September 2014. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages 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.
