Two outlets report that climate change could significantly increase overheating risk for homes in Sydney, even those built to current standards. Phys.org notes that Sydney has already experienced extreme heat, citing a record Greater Sydney temperature of 48.9°C in January 2020 at Penrith. The Conversation adds that modelling focused on apartment comfort shows future periods of excessive indoor heat could become more frequent. It reports that apartments built to today’s standards may be too hot for extended stretches, with estimated overheating lasting about four weeks per year in Redfern and more than seven weeks per year in Penrith by 2050.
Together, the sources highlight both the existing heat extremes in the region and the projected intensification of hot-weather conditions that could reduce thermal comfort in residential buildings. They do not dispute that Sydney experiences high temperatures; instead, they emphasize that by mid-century, heat exposure could last longer and occur more often, affecting apartment dwellers in different suburbs.
