From tropical rainforests to temperate coastlines, South Australia spans a range of climates that shapes everything from agriculture to tourism. Here's the weather across 22 of the state's major towns and cities, with comprehensive climate data including monthly temperatures, rainfall patterns, humidity, solar exposure, and our proprietary comfort score.

Climate varies dramatically across South Australia. Here are some key extremes at a glance, identified from average annual temperature and rainfall data across 22 cities and towns in the dataset.

All data in this dataset comes from the Open-Meteo Historical Weather API, sourced from official weather station networks and reanalysis models. Data reflects averages across the full 2024 calendar year. Each city includes monthly averages for maximum and minimum temperatures, total rainfall, the number of rainy days, solar exposure measured in megajoules per square metre, and relative humidity at the time of maximum daily temperature. Our comfort score synthesises these factors to rate each month from 1 (harsh conditions) to 10 (ideal), helping you find the best times to visit.

The comfort range in South Australia tells the story: Oodnadatta scores 5.4 while Ceduna leads with 7.9. The statewide average is 6.5. That's close to the national average of 6.2, though individual cities vary widely.

The spread from 5.4 to 7.9 reflects genuine climate diversity within South Australia. Elevation, distance from the coast, and latitude all play a role in shaping local conditions. Coastal cities average a comfort score of 6.9 compared to 6.5 inland, reflecting the moderating influence of the ocean on temperature extremes and humidity.

Each city page includes month-by-month climate data, comfort scores, packing recommendations, and detailed seasonal analysis. You'll also find comparisons to the state's capital city and links to explore weather patterns month by month.
