The 2011-2012 La Niña has ended. La Niña conditions in the tropical Pacific transitioned to neutral (neither El Niño nor La Niña) conditions in early April 2012. Model forecasts and expert opinion suggest that neutral conditions are likely to continue into the Northern Hemisphere summer (austral winter). For the second half of 2012 a return of La Niña is unlikely, while neutral or El Niño conditions are currently considered to have equal chances of occurring. National Meteorological and Hydrological Services and other agencies will continue to monitor Pacific Basin conditions and outlooks to assess the most likely state of the climate during 2012.
