Adelaide Metro & Hills in July 2014: Mild and wet

July saw above average rainfall across Adelaide, with the Kent Town office recording 99.6 mm (+31% above the long-term July average). Rainfall was recorded over 16 days (the July average is 16 days), with the heaviest rainfall occurring between the 8th and 11th, the 17th and 18th and again on the 24th. Vigorous cold fronts delivered daily totals in excess of 15 mm on these days and were also associated with very strong winds and isolated thunderstorms. Another strong cold front to the south of the Great Australian Bight produced isolated squally showers and strong wind gusts across the Adelaide region on the 31st. Monthly rainfall totals were generally between 80 and 110 mm across metropolitan locations while many locations in the Adelaide Hills received totals in excess of 160 mm. The wettest location was Uraidla in the Adelaide Hills with a monthly total of 261.mm, with 48 mm observed in the 24 hours to 9am on the 9th.

Both monthly mean maximum and minimum temperatures were near average across the Adelaide metro and hills region. Above average temperatures were generally experienced in the days preceding the passage of the cold fronts as warm northerly winds were directed across the state. Daytime temperatures were coolest in the cold airmass that followed the passage of the fronts. The Adelaide (Kent Town) office recorded its coldest day on the 9th, with a maximum of just 10.9 °C, which was the coldest July day for Adelaide in 9 years. Mount Lofty observed the coldest day for any location on the 9th, with a maximum of just 5.7 °C. The third week of July saw generally warmer than average daytime temperatures for most locations which remained to the end of the month.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Adelaide Metro & Hills 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 9 am on Friday 1 August 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 20 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.
