WESTERN and central Australia could experience a wet Spring while eastern and northern States face a neutral season.
That's according to the Bureau of Meteorology's (BoM) seasonal outlook for September to November released today.
There is an increased chance of a wetter-than-average season over much of southern and central WA, the southern NT, SA and extending into parts of western NSW, Victoria and Queensland.
In far north Queensland, Spring is likely to be drier than average.
Most of eastern Australia has a roughly equal chance of a wetter or drier season.
Warmer nights are likely for most of Australia, with warmer days likely along the east coast and far southwest WA.
BoM says the current outlook reflects the record warm sea surface temperatures in the Indian Ocean, and the El Niño in the Pacific.
Climate models suggest that El Niño is likely to peak towards the end of 2015, weakening in the first quarter of next year.
BoM says at this time of year, models have little skill forecasting beyond the following autumn, the typical El Niño-Southern Oscillation transition period.
The Indian Ocean Dipole (IOD) is currently neutral.
