What defines Harrisdale’s weather?
The suburb sits on the Swan Coastal Plain, roughly 25 km southeast of the Perth CBD. Summer (December–February) averages around 30–32°C, with occasional heatwaves pushing past 40°C when easterly winds bring inland heat. Winter (June–August) sees daytime highs near 17–19°C and most of the annual rainfall (about 800 mm) arrives from May to August. The afternoon sea breeze, known locally as the “Fremantle Doctor”, often moderates summer heat.
