Perth, Australia’s sunniest capital city, enjoys a hot-summer Mediterranean climate (Köppen Csa) marked by distinct seasonal variations. Summers, stretching from December to March, are typically hot, dry, and sunny, with February being the hottest month. The city receives an impressive 3,200 hours of sunshine annually, averaging 8.8 hours a day and around 138 clear days per year.

Summer temperatures often exceed 35°C (95°F) on about 26 days annually, with occasional peaks above 40°C (104°F). The highest recorded temperature reached 46.2°C (115.2°F) on 23 February 1991, while Perth Airport registered an even higher 46.7°C (116.1°F) the same day. Despite the heat, Perth residents often find relief from the cooling “Fremantle Doctor,” a sea breeze that sweeps in most afternoons, quickly lowering temperatures.

In contrast, winters are mild and wet, with most rainfall occurring between May and September. Temperatures can drop below 5°C (41°F) during clear nights, and frosts occasionally form in outer suburbs like Jandakot and Kalamunda. The city’s lowest recorded temperature was −0.7°C (30.7°F) in June 2006, while the coldest metropolitan

The city’s lowest recorded temperature was −0.7°C (30.7°F) in June 2006, while the coldest metropolitan reading was −3.4°C (25.9°F) at Jandakot Airport. Although snow has never fallen in central Perth, light snow was last observed in the Perth Hills in 1968.

Over recent decades, Perth’s rainfall trends have shifted significantly. Since the mid-1970s, winter rainfall has declined, while extreme summer weather events have become more common. Notable examples include the 120.6 mm downpour on 8 February 1992, the 114.4 mm tropical low of 10 February 2017, and the remnants of Cyclone Joyce, which delivered 96.2 mm on 15 January 2018. A severe thunderstorm in March 2010 also caused widespread damage with large hail and 40 mm of rain.

While Perth remains one of the sunniest and most livable cities in Australia, the ongoing climate variability and changing rainfall patterns highlight the need for adaptive strategies to preserve its unique weather balance.
