Rising temperatures

Written by       Illustrated by NIWA

Ten New Zealand climate stations have operated from the same locations since at least the 1940s. The charts shown present data collected from these sites to address a simple question: Which years were warmer and cooler than the station’s average temperature?

The results are stark. Over the past 80 years, these places have recorded a warming trend close to 1°C. Aotearoa is getting hotter.

NIWA scientists forecast these trends will continue. Likely impacts include more intense winter rainfalls, drier summers and sea-level rise.

Charts show annual average temperature anomalies. Station averages are calculated from the 1961-90 climatalogical period. Positive bars represent warmer years than normal. Negative bars show cooler years. Gaps in a chart denote years with incomplete climate records.
