NINO3.4 Index
The NINO3.4 index is one of several El Niņo/Southern Oscillation (ENSO) indicators based on sea surface temperatures.
NINO3.4 is the average sea surface temperature anomaly in the region bounded by 5°N to 5°S, from 170°W to 120°W. This region has large variability on El Niņo time scales, and is close to the region where changes in local sea-surface temperature are important for shifting the large region of rainfall typically located in the far western Pacific.
An El Niņo or La Niņa event is identified if the 5-month running-average of the NINO3.4 index exceeds +0.4°C for El Niņo or -0.4°C for La Niņa for at least 6 consecutive months.

Winter is Coming: Chilly day for Sydney, rain pelts eastern seaboard
17:22 AEST Just as we forecast yesterday, a coastal trough has deepened along the NSW and southeast Qld coasts as a low in the Coral Sea continues to inch closer to Qld. The trough has brought some interesting weather to NSW in the past 36 hours or so, particularly along the coastal fringe, giving those New South Welshmen a “Stark” Game of Thrones reminder: winter is coming.
- 11:54 AEST We need to talk about drainage
- 11:48 AEST A very wet weekend for southeast Qld, northeast NSW
- 10:07 AEST Southerly surges across the southeast
- 13:20 AEST Generation gone with the wind
