4.7.4.2. Change in average temperature
Historical monthly average temperatures (during the climate change projection reference period, 1980-
1999) and projected changes for the Adelaide Airport meteorological station in 2030 and 2070 are given
in Figure 4.14.
Projected mean minimum temperatures in 2030 are only slightly greater than those recorded during the
1980-1999 reference period during autumn and winter. The difference between the two is slightly greater
during summer. Under the most extreme scenario (2070 high emissions, 90th percentile projections),
temperatures are projected to increase by 3.5 - 4.5°C.
Projected changes in maximum temperatures are greater in summer than in other seasons. By 2070,
under the most extreme scenario, mean maximum temperatures are projected to range between 18.3 and
32.7°C, compared with 14.9 and 28.2°C during the 1980-1999 reference period (Figure 4.14).
