Adelaide in January 2015: cool days, warm nights, high humidity

Despite above average temperatures during the first week of January daytime temperatures for the month as a whole were cooler than average across the Adelaide region, resulting in the coolest January days since 2004. Humidity levels were also high throughout the month, the most humid January conditions since 2004. Night-time temperatures were slightly warmer than average. Daytime temperatures cooled significantly during the second week, as an upper level trough and a burst of tropical activity produced moderate to heavy rainfall for most locations across the metropolitan area and hills regions between 8 to 11 January. This continued on 13 January as a low pressure system located south of the State extended another trough across the region. The rainfall from these systems resulted in the monthly total rainfall to exceed two to three times the January average across the Adelaide Hills, with several locations having their wettest January in more than 20 years. A persistent south-easterly airstream along southern coasts resulted in milder conditions continuing through the second half of the month.

  • Tropical activity and low pressure systems bring significant rainfall in the second week
  • Adelaide Hills records wettest January in more than 20 years
  • Adelaide's coolest but most humid January days in 11 years

Values over 100 mm have been rounded to the nearest whole millimetre.
Days marked with - have a rainfall report of zero; days left blank have no rainfall report (which often indicates no rain fell).

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Adelaide 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 11 am on Monday 2 February 2015. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

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.

The ACORN-SAT dataset is used for temperature area averages.
