Perth has a Mediterranean climate, with hot, dry summers and cool, wet winters. In summer (November to March) temperatures average between 58°F (15°C) and 88°F (31°C), occasionally reaching as high as 105°F (41°C). Luckily the sea breeze known as the 'Fremantle Doctor' somewhat tempers the heat. Rainfall during this period is low, with an average of only three to four days each month receiving rain. Winter in Perth (June to September) is cool without getting unpleasantly cold, generally staying between 46°F (8°C) and 68°F (20°C). This is the wettest time of year, with roughly half the days in each month getting rainfall. Tropical cyclones do hit Perth, however this is very rare.
