The rainfall percentile analyses (deciles) use a reference period from 1900 to 2002 containing quality controlled data from the climate data bank. The data used for the rainfall percentile analyses are based on preliminary real time data which have not been verified and only limited quality control checks have been performed.

The rainfall pattern for the November to January period strongly reflects the 1-month January pattern. Below to very much below average totals occurred across most of the eastern states, including Tasmania, with a large area of central to eastern Queensland enduring record low falls for this period. Elsewhere, below average falls were confined to parts of the west and central NT and the far west of WA.

Very much above average to record falls occurred about the south and west of the Gulf of Carpentaria, almost solely as a result of a slow-moving monsoonal depression in January. Much of central and southern WA and adjacent parts of western and southern SA, also recorded above to very much above average rainfall fro the November to January period.
