Darwin: HeatWatch projects up to 308 days over 35°C per year by 2090
The Bureau of Meteorology issued a severe heatwave warning for Darwin, ahead of a December week with six days over 35°C. Severe heatwaves can be dangerous for many people, especially older people, babies, children, pregnant and breastfeeding women, people with medical conditions and people who are unwell.
Darwin has a historic baseline averaging 15 days over 35°C per year (based on 1981-2022 data). More recently, the area experienced 40 days of 35°C+ heat in 2021.
According to CSIRO-BoM projections, under a high emissions scenario, Darwin can expect averages of up to 308 days per year over 35°C – more than 20 times more than the historic baseline – and up to 7 annual days over 40°C, by 2090. Yet, if emissions are drastically limited, Darwin could keep the average number of days over 35°C to just 133 in 2090 – a dramatic improvement compared to a high emissions scenario.
