SwellMap’s temperature anomaly map showing water temperatures in the Cook Strait are up 1.45°C above average on the 23rd of December 2022.
Now available: Ocean temperature forecast shows if water is colder or warmer than expected
As the climate changes, our seas are getting warmer. A new forecast developed by the MetService-led Moana Project is now available on SwellMap, showing the difference between actual and expected sea surface temperatures for New Zealand waters. In science terms, this difference between actual and expected temperatures is called the ‘anomaly’.
This 7-day forecast shows a map of the difference between actual and expected temperatures for that specific day of the year, with red colouring indicating warmer than usual conditions and blue colouring colder than usual conditions. Users can click on the map to see the exact temperature differences for any location.
