Geography

Port Lincoln has a contrasting coastal landscape, ranging from sheltered waters and beaches, to surf beaches and rugged oceanic coastline. The Great South Australian Coastal Upwelling System brings cold, nutrient-rich water into nearby waters of the Great Australian Bight and Spencer Gulf. These upwellings support lucrative fisheries, including that of the southern bluefin tuna and sardine. Port Lincoln has a warm-summer Mediterranean climate (Köppen: Csb). The climate is highly variable due to the town's position between the Outback and Southern Ocean. Summers alternate between frequent southerly sea breezes (keeping maxima under ), with occasional northerly heatwaves (that raise the temperature to well over ). Meanwhile, winters are cool and cloudy, with frequent drizzle, showers and cold fronts, albeit with frost being very rare. There is moderate seasonal temperature variation and seasonal lag, with average maxima ranging from in January to in July, while average minima vary from in February to in August. Average annual rainfall is rather low, , occurring within 127.1 rainfall days, and the wettest month on record was in June 1981. Despite the low intensity of rainfall: there are 154.5 cloudy days and only 57.2 clear days annually. Extreme temperatures have ranged from on 16 July 2016 to on 24 January 2019.
