Heat Risk in Middle Swan, WA: 2026 Assessment

Middle Swan in Western Australia faces elevated extreme heat risk. The Bureau of Meteorology (BOM) reports that Australia's average temperature has increased by approximately 1.5 °C since 1910, with the frequency of extreme heat days rising across most regions.

The urban heat island (UHI) effect can make built-up areas of Middle Swan warmer than surrounding rural areas, particularly on summer nights. Dark roof materials, limited tree canopy cover, and heat-absorbing surfaces contribute to localised heat stress that varies by property.

The urban environment in Middle Swan contributes to the urban heat island effect, increasing temperatures during heatwaves.
