Perth enjoys the title of Australia’s sunniest state capital and is rightly famed for its enviable weather. In summer it is almost always sunny, dry and hot, while winter is a bit wetter and mild. You need to be very aware of the strong sun on Perth especially in summer. Try to avoid being in the sun in the middle of the day and when you are in the sun make sure it is not for long. Also be sure to protect yourself with sun cream and a hat and t-shirt.
During summer Perth temperatures are very hot and rainfall is rare. It is classic Aussie beach weather. Summer days see average highs of 32°C and lows of 17°C. Temperatures can however get much higher – often soaring into the 40s for a few days each summer. It is unusual to see summer temperatures drop below the mid-teens.
Winter in Perth is mild and wet. Temperatures vary between 8°C and 18°C in winter months, only occasionally gets below 2°C or 3°C at night. You never get snow but winter is when most of the rain falls. June, July and August account for over half of the yearly rainfall.
Spring and Autumn
Spring and autumn are both very pleasant times in Perth with comfortable temperatures and low rainfall. Daily highs can reach into the low to mid 20s and it never gets cold. Rain is low especially in autumn. The start of spring (September) can see a little rain but it drops away sharply as the dry, hot summer approaches.
