Daily mean temperatures at the Crater Lake since 2020 with the coolong trend (image: GNS Science/GeoNet )
The Crater Lake usually experiences two to three heating and cooling episodes within any 12-month period. During these cycles, the lake temperature typically rises to 30–40 °C before cooling back to 10–15 °C. Since reaching 41 °C in May 2022, there have been five subsequent heating episodes, with each peak—except one—lower than the previous, indicating an overall downward trend in maximum lake temperatures.
The most recent cycle began at 10 °C in early July and peaked at only 17 °C in late August before declining again. The lake is currently 13 °C.
Although the three-year trend shows progressive cooling, substantial volumes of volcanic gas continue to be released from the active vent beneath the lake. This demonstrates that an open pathway persists
