South Australia in November 2023

Rainfall

• Rainfall in November was below average across Kangaroo Island and western and northern parts of the Eyre Peninsula, but above average across the Greater Adelaide region, eastern districts and parts of the far north.
• For the South Australia as a whole, rainfall was 10.5% above the long-term (1961-1990) average for November, the state's driest since 2020.
• The first three weeks of the month were particularly dry, until a broad, low pressure trough produced widespread showers, rain and thunderstorms over agricultural areas and adjacent parts of the Flinders and North East Pastoral districts in the final week of November.
• A severe thunderstorm brought heavy rain that resulted in Naracoorte Aerodrome recording 71.4 mm in the 24 hours to 9am on the 25th, which was the highest November daily rainfall on record for both the current and the former observation sites in the town and an annual record for highest daily rainfall for the current site (previous record was 69.4 mm on 14 January 2011).
• Multiple sites had their highest November daily rainfall on record during the last week of the month, which also resulted in some sites having their highest total November rainfall on record or their highest total November rainfall for at least 20 years.

• Streaky Bay had its lowest November mean daily minimum temperature on record and Adelaide (West Terrace / ngayirdapira) had its lowest November mean daily minimum temperature for at least 20 years.
• With above average mean maximum and mean minimum temperatures across northern parts of the state, Maree reported its equal-highest November mean temperature on record.
