Location and Climate Influences
Adelaide sits at 34.9 degrees south latitude, roughly equivalent to Los Angeles or Casablanca in the northern hemisphere. The city’s Mediterranean climate is shaped by three geographic features: the Gulf St Vincent to the west (moderating coastal temperatures), the Mount Lofty Ranges to the east (creating a rain shadow that keeps the city drier than Melbourne or Sydney), and the vast Australian interior to the north (the source of summer heatwaves when northerly winds push desert air over the city). The result is a climate with sharper seasonal contrasts than coastal Sydney: hotter summers, cooler winters, and roughly half the annual rainfall of Sydney or Brisbane.
