Some El Niño-like atmospheric patterns have also been present. Model predictions and expert opinion indicate a 60-65% chance that El Nino will be present during June-August 2019. Chances for El Niño continuing into the following season of September-November fall to near 50%.Click to see full answer. Accordingly, are we in an El Nino year 2019?August 2019 El Niño Update: Stick a fork in it. The El Niño of 2019 is officially done. Near-average conditions in the tropical Pacific indicate that we have returned to ENSO-neutral conditions (neither El Niño or La Niña is present).Furthermore, is it a El Nino or La Nina year? El Niño and La Niña episodes typically last nine to 12 months, but some prolonged events may last for years. While their frequency can be quite irregular, El Niño and La Niña events occur on average every two to seven years. Typically, El Niño occurs more frequently than La Niña. Also question is, when’s the next El Nino? 2014, 2018 predictions The next expected El Nino, due to peak in late 2020, could push global average annual temperature rise to a new record in 2021, the researchers said. Air temperature rise lags Pacific warming by about three months, they noted.Is 2019 a La Nina or El Nino year?(image at left) Difference from average sea surface temperatures at the equator in the tropical Pacific in November 2019. El Niño and La Niña are the warm and cool phases of a recurring climate pattern across the tropical Pacific—the El Niño-Southern Oscillation, or “ENSO” for short.
