Australia on alert for a third La Nina event this summer

18 August 2022

Another wet summer may be on the cards for parts of Australia, after the Bureau of Meteorology moved the ENSO Outlook to a La Niña alert status.

This status change follows a renewal of cooling in the tropical Pacific Ocean towards La Niña thresholds over recent weeks, as well as the persistence of the Southern Oscillation Index (SOI) at La Niña levels and strengthened trade winds at La Niña levels. Climate models indicate further cooling is likely, with four of seven models suggesting La Ni Niña a could return by early-to-mid southern hemisphere spring.

If another La Niña eventuates this summer, it will be the third in a row.
