Adelaide in summer 2015-16: temperatures above average; rainfall near average

Total summer rainfall across Adelaide was average or above, but most days were dry in the city. Both summer daytime and night time temperatures were warmer than average across Adelaide.

  • Dry for most of the summer period
  • A few wet days ensure average totals
  • Temperatures above average
  • Fourth warmest summer for the city

It was generally a dry summer, but the summer total for most locations came in average or above average because of some very wet days. Nearly half of the summer total for most locations in the Adelaide region was recorded in just 3 days (between 29 and 31 January) as a low pressure trough moved across southern parts of the State. Uraidla was the wettest station in the area with a summer total of 157 mm, 44 mm of which was recorded on 30 January.

All stations across the Adelaide region recorded mean maximum temperatures that were warmer than the long-term summer average, in some cases by more than two degrees. Minimum temperatures were also warmer than average, with most locations reporting nights that tended one or two degrees warmer than normal. High temperatures occurred in December, that saw city record 7 days over 40 °C. Record December heat and a hotter than average January resulted in a summer daytime average for Adelaide of 31 °C, ranking summer 2015-16 as the fourth warmest summer on record for the city, and warmest since 2000-01. A vigorous cold front at the beginning of December saw Adelaide (Kent Town) record its lowest summer temperature on record.

Notes

The Seasonal climate summary lists 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.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 10 am on Tuesday 1 March 2016. 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.
