Australia Climate Forecast is Wet East Coast Much of 2025

The Australia season 1-4 ahead outlook is updated. The forecast is valid for meteorological autumn 2025 through summer 2025-26. The forecast is based on an ENSO climate favoring La Nina, neutral Indian Ocean dipole, and the influence of marine heat waves either side of the continent. Forecast highlights include a persistent wet climate in southeastern Australia likely through next summer while next winter is warmer than normal.

Upper Air Pattern Changes: Wetter Argentina

This week, strong subtropical high pressure stretching across mid-continent from marine heat waves either side of South Americ render extreme heat from Argentina to Southeast Brazil. However, latest forecasts split the subtropical ridge allowing weak low pressure to form over Bolivia which lifts tropical rains from northwest continent southeastward into Argentina during the medium range.

Is There Sudden Stratospheric Warming Ahead in Early March?

Utilizing CFS V2 extended range forecasts of the stratosphere there is not an obvious sign of an emerging sudden stratospheric warming (SSW) event during late FEB/early MAR. The ECM forecast is not available. HOWEVER, a major slowdown of the global atmospheric angular momentum (GLAAM) is in the forecast through mid-March. When -GLAAM occurs, the mid-latitude upper-level pattern has the tendency to produce amplified low-pressure troughs.
