In order to calculate how the average temperature for 2021 compares to previous years, we can look at NIWA's 'seven-station' temperature series (which extends back to 1909). With an average annual temperature of 13.56°C, 2021 has become Aotearoa New Zealand's warmest year on record, surpassing the previous record set in 2016. This long running record shows New Zealand's average annual temperature has increased by about 1°C over the past 100 years.By plotting the seven-station series as anomalies we can see how the annual temperature compares to a long term average._________________Item Page Created: 2021-12-20 02:03 Item Page Last Modified: 2025-04-05 20:31Owner: fedaeffn_NIWA
