South Australia in October 2015: Dry with above average temperatures

In South Australia, most of the State saw below-average rainfall for October. Rainfall was very much below average across much of the agricultural districts, with the several locations in the lower southeast reporting their driest October on record. Along with the dry conditions, both maximum and minimum temperatures were very much above average to highest on record across the entire State.

• Very much below average rain across the state
• Warmest days and nights on record for the State
• Early season temperature records
• Highest mean temperature anomaly for any month
• Highest mean maximum temperature anomaly for any month

October rainfall was very much below average for South Australia as a whole, with most parts of the State recording less than 20% of the long-term October average. High pressure dominated the weather, resulting in a lack of rain bearing fronts reaching the State. The lack of rain saw this October rank as the 7th driest on record, persisting September's drier than average conditions across southern districts. Several stations in the southeast reported their lowest total October rainfall on record.

Both the statewide mean maximum and mean minimum temperatures were warmer than average across much of the State, which resulted in the warmest October on record. The month started with a high pressure ridge slowly tracking across southeast Australia as a pre-frontal trough approached South Australia from the west, resulting in a northwesterly airstream being directed across southern districts. By October 3, temperature anomalies in excess of +12 °C extended across large areas of South Australia with many stations recording early season temperature records. As the warm days and nights persisted during the month, many stations reported their warmest October on record. The statewide mean maximum temperature, mean minimum temperature anomalies were all more than 1 °C above their previous records set in 2014 and 1940 respectively.
