Seasonal Climate Outlook

Bureau of Meteorology seasonal climate outlook

The Bureau of Meteorology's climate forecast system for monthly and seasonal climate outlooks is called the Australian Community Climate Earth-System Simulator – Seasonal (ACCESS–S). It is a dynamical (physics-based) forecast modelling system and is a collaboration between the Bureau of Meteorology and the UK Meteorological Office.

The Bureau of Meteorology’s current seasonal outlook is indicating a less than 40% chance of exceeding median rainfall for January to March 2019 for the SWLD. Predictive skill is moderate to good (55-75% consistent).

Temperature outlooks January to March 2019 from the Bureau indicate 50-75% chance of above average day-time maxima for the SWLD. Skill is moderate to good at 55-75% consistent. Minimum temperature outlooks indicate 30-60% chance of above average night-time minima (lower chances along the coast) , with skill mostly moderate at 50-65% consistent.
