How does the local geography affect Hamilton Hill weather?
Hamilton Hill is a coastal suburb, about 4 kilometres inland from Cockburn Sound. The ocean moderates temperatures, keeping summer highs a few degrees lower than inland Perth suburbs. In winter, the proximity to water can mean more cloud and drizzle, especially when a low-pressure system sits over the southwest.
