Bureau of Meteorology seasonal climate outlook

The Bureau of Meteorology's climate forecast system for monthly and seasonal climate outlooks is the Australian Community Climate Earth-System Simulator – Seasonal (ACCESS–S1). 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 neutral (45-60%) chance of exceeding median rainfall for autumn, March to May 2019 for the SWLD. Predictive skill is poor to moderate (45-65% consistent).

Temperature outlooks autumn, March to May 2019, from the Bureau indicate an over 80% chance of above average day-time maxima for the SWLD. Skill is mostly low to moderate at 45-65% consistent. Minimum temperature outlooks indicate greater than an 80% chance of above average night-time minima for the SWLD, with skill mostly poor at 45-55% consistent.
