The RMM signal remains weak. This incoherent MJO signal is unlikely to have any effect in northern Australia at this time of year.

The next passage of the MJO is expected late October, and at this time of year could be reasonably expected to initiate (pre-monsoon) early summer rains in the north.

In Australia, there is less direct impact from MJO passages during our winter/early spring. For example, during Phases 5 and 6 the southern grain belt (south eastern Australia) could expect enhanced chances of rain, and the western grain growing region winter rainfall is enhanced during MJO Phases 7 and 8.

More 'weak' MJO Index signals, when Phase cannot be determined, are recorded during Austral winter.
