Sea surface temperatures in the southern Tasman Sea rose to exceptionally high levels in late 2017 and early 2018. These temperatures were far above any others previously observed at that time of year in the region, and extended west from New Zealand to Tasmania and mainland southeast Australia. In parallel with this, land temperatures were well above average in areas near the Tasman Sea warm anomalies, with many records set both in New Zealand and in southeast Australia (especially Tasmania).
