Hamilton Hill is currently experiencing conditions as shown in the live forecast above, with a coastal influence from nearby Cockburn Sound. This south-west suburb of Perth typically sees mild, wet winters and warm, dry summers, moderated by afternoon sea breezes.
What is the typical weather pattern for Hamilton Hill?
Hamilton Hill sits just inland from Fremantle, so its climate is shaped by the Indian Ocean. Summers (December–February) bring average maximums around 29°C, often cooled by the Fremantle Doctor sea breeze in the afternoon. Winters (June–August) are cooler and wetter, with July maximums near 18°C and most rain falling from cold fronts moving across the south-west. The suburb’s position means it can be a few degrees cooler than inland Perth on summer afternoons.
How does the local geography affect Hamilton Hill weather?
The suburb lies on the Swan Coastal Plain, with the coast just 4 kilometres west. This proximity means fog and low cloud can linger on winter mornings, while summer evenings often stay mild due to the ocean’s heat retention. The nearby Beeliar Regional Park and lakes can also trap localised moisture, leading to slightly higher humidity than areas further east.
Does Hamilton Hill get the Fremantle Doctor?
Yes. The afternoon sea breeze, known locally as the Fremantle Doctor, regularly reaches Hamilton Hill on summer days, dropping temperatures by 5–10°C. It typically arrives between 1pm and 3pm.
Is Hamilton Hill weather different to central Perth?
Generally yes. Hamilton Hill is often 2–3°C cooler than the Perth CBD on summer afternoons due to its coastal proximity. In winter, it can be slightly warmer overnight because of the ocean’s moderating effect.
