Wednesday, 30 July 2014 - Monthly Climate Summary for Northern Territory - Product code IDCKGC12R0
From 13-15 July a northwest cloudband brought some rainfall to the Alice Springs District and many stations recorded 20-40 mm from the 4 day event. The 14th was the wettest day with 31 mm being recorded at Mount Denison and Yuendumu. The rest of the Territory experienced typical dry season conditions with most locations reporting 0 mm rainfall for the month. Overall the mean rainfall for the NT was 9.5 mm, which is 38% above the mean for July. There were no new rainfall records set for July.
In general maximum temperatures were average to above average for the NT this month while minimum temperatures were average to below average. While under the shadow of a northwest cloudband on the 13th, daily maximum temperatures were especially cool across central Australia. Alice Springs Airport measured the lowest daily maximum with 7.5 °C and three locations set new low daily maximum temperature records. This cool spell was both brief and isolated to the southern NT such that overall the maximum temperature for the month was 0.7 °C above the long term average for July. Several periods of southerly or south easterly winds kept the minimum temperatures (and humidity) low across the Top End. On average, minimum temperatures in the Northern Territory were half a degree below average for July.

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 Wednesday 30 July 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
(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.
