Just taking a quick look at the latest January to March rainfall and temperature three month Outlooks from the Australian Bureau of Meteorology (BoM). I have linked to the originals for rainfall and temperature. Note these forecast maps were issued on 17 Dec 08.
I have made the actual rain and temperature anomaly maps at this useful page. You can choose rain or temperature (max or min) for various periods or parameters. I am not saying medium term forecasting is easy but I am puzzled the BoM maps are often so EXACTLY wrong.
|Rain forecast||Actual rain deciles, blue wet, red dry|
|Max temperature forecast||Maximum temperature anomalies|
|Min temperature forecast||Minimum temperature anomalies|
