Climate change in Auckland

The Auckland heat vulnerability index was developed as part of the climate change risk assessment (CCRA), used as evidence for Auckland Council’s Climate Action Framework (ACAF). It used national climate change projections and developed a range of scenarios for climate change impacts, developed by NIWA for Auckland Council.

The representative concentration pathway (RCP) 8.5 illustrates a business as usual scenario. Under RCP 8.5, most of the region will experience a mean annual temperature increase of 3.25-3.75°C (Tmax), by 2110.

In addition to the mean rise, the number of hot days will increase. In Auckland a hot day is defined as where the daily maximum temperature exceeds 25°C (Tmax >25°C). Compared to today, up to four times as many hot days per year are expected by the end of the 21st century across Auckland.
