ENSO State and Outlook

NOAA Climate Prediction Center products read daily and served together: the Oceanic Niño Index for every three-month season since 1950 with El Niño and La Niña episodes under NOAA's five-season rule, the weekly Niño-1+2, 3, 3.4 and 4 indices since 1981, the monthly ENSO alert status and synopsis, and the official probability and strength outlooks for the next nine seasons. PRISM archives every monthly outlook by issue month so a forecast can be read against what followed.
