Perth enjoys a Mediterranean climate with warm, sunny weather for most of the year.

There is very little rainfall in summer. Rainfall comes mainly in winter although, even in winter, Perth usually enjoys plenty of pleasantly warm sunshine.
Perth can be windy, especially in the hotter months. The “Fremantle Doctor” is a sea breeze that brings relief from Perth’s high summer heat. It can, however, also blow sand around and, when particularly strong, can be rather hazardous for people on the beach.
On a few days each summer, temperatures rise above 40 degrees Celsius. By any stretch of the imagination, these are extreme temperatures. The best thing you can do on these days is stay at home with your air-conditioning on maximum.
Sea temperatures around Perth are very pleasant.
