On 1 July 2025, NIWA merged with GNS Science to become Earth Sciences New Zealand.

Sea Surface Temperature Update

To give insights to sea surface temperatures, NIWA scientists have combined predictions from ten climate models from institutes around the world.

Forecasting sea surface temperatures several months in advance is challenging. To give us insights into what might happen around Aotearoa New Zealand in the months to come, NIWA scientists have combined predictions from ten different climate models from institutes around the world.

    Sea Surface Temperature Forecasts February - July 2023

    Amid a changing climate, global sea surface temperatures are increasing. This will be associated with more frequent and intense marine heatwave events (which are defined as being an extended period of extremely warm ocean temperatures that can extend up to thousands of kilometres).
