A negative Indian Ocean Dipole (IOD) event is under way. The IOD index has been very close to or exceeded negative IOD thresholds (i.e., at or below -0.4 °C) over the past eight weeks. All climate model outlooks surveyed indicate that negative IOD conditions are likely to continue into late spring (October-November). A negative IOD event is associated with above average winter to spring rainfall for much of Australia.
