ENSO state for the November-April season between 1995/1996 and 2009/2010.

Estimated using tercile analysis of the NINO34 SST Index for Nov-Apr 1995/6 through Nov-Apr 2009/2010. Average SST for each seasonal estimate (e.g. Nov 1997 - Apr 1998) is given in parentheses. The NINO34 SST index is an oceanographic indicator of large-scale ENSO activity [58], and is higher (lower) during ENSO warm (cold) phase conditions; warm (cold) phase years are expected to be associated with drier (wetter) conditions in northern Queensland [35], [36].
