Tuesday, 1 June 2010 - Monthly Climate Summary for Northern Territory - Product code IDCKGC12R0
Record breaking average minimum temperatures were recorded over the Top End, while elsewhere night-time temperatures were warmer than normal. Most stations in the Victoria District recorded their wettest May ever, rainfall over the rest of the Territory was above average.
Rainfall in the Darwin-Daly was very much above average for the month with some stations recording their wettest May ever. Further east, in the Arnhem District the majority of stations recorded average rainfall. Over the Roper-McArthur District, Gorrie recorded its wettest May on record while the rest of the stations recorded above average to very much above average rainfall. The Victoria District was remarkably wet with almost half of the stations recording their largest May rainfall totals ever. Rainfall in the Barkly District was generally very much above average while further south in the Alice Spring District, rainfall was mostly above average.
The wettest overall was 187.8 mm at Bradshaw AWS, followed by 152.8 mm at Upper Adelaide River and then 151.0 mm at Port Keats Aero.Some sites had their highest total May rainfall on record.

Over most of the Top End, the mean maximum temperatures were average to very much above average. Further south, average daytime temperatures in the Alice Springs Districts were mixed with some stations reporting cooler than average maximums and others reporting warmer than usual maximums. In the Roper-McArthur District mean maximum temperatures were also mixed, however, all stations recorded average maximum temperatures within 1°C of their long-term mean.
The hottest day was 37.4 °C at Urandangi on the 4th, followed by 36.7 °C at Bradshaw AWS on the 3rd, followed by 36.4 °C at Timber Creek on the 3rd, and Bradshaw AWS and Timber Creek on the 5th.

The coldest day was 14.9 °C at Alice Springs Airport on the 20th, followed by 15.0 °C at Arltunga and 15.5 °C at Yulara Aero AWS on the 20th.Some sites had their coldest May day (lowest maximum temperature) on record.
All stations in the Darwin-Daly District and most in the Arnhem District, recorded their warmest May average minimum temperatures ever. In the Roper-McArthur and Victoria Districts, mean minimum temperatures were generally very much above average with some stations recording their warmest May nights ever.

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.
This statement has been prepared based on information available at 1 pm on Tuesday 1 June 2010. 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
the years 1800 to 2008.
They are not shown for sites with less than 10 years of record in that time, 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.
