Heat Risk in Upper Coomera, QLD: 2026 Assessment

Upper Coomera in Queensland 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 Upper Coomera 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.

January is the hottest month, with average maximum temperatures exceeding 31 degrees Celsius. Heat stress events are becoming more frequent.
