Sea surface temperature anomalies in critical parts of the Pacific Ocean have warmed enough for NOAA to declare anEl Niño eventto be underway. An El Niño is one of three possible phases of the El Niño-Southern Oscillation (ENSO) and forms when sea surface temperature anomalies reach 0.5...

El Nino and La Nina are phases of changing sea-surface temperatures in the eastern Pacific Ocean that influence global weather. The current El Nino, ongoing since 2023, is expected to weaken and shift to neutral conditions by April-June 2024, according to NOAA’s Climate Prediction Centre. Thi...
When sea surface temperature anomalies in parts of the Pacific reached a mean temperature of 0.5 degrees Celsius (0.9 degrees Fahrenheit) in June 2023, the first El Niño in nearly four years was considered to be underway. According to data compiled by NOAA, the event became strong, with av...

According to NOAA El Nino and La Nina episodes typically last nine to 12 months, but some could last for years. El Nino and La Nina events occur on average every two to seven years, with El Nino appearing more frequently than La Nina. ...
La Niña started in 2020, when it helped nurture arecord hurricane season. The weather system also contributed to a 2021 hurricane season resulting in$70 billion in damagesand more than 160 deaths, NOAA said. Studies have shown La Niña is more expensive to the U.S. than El Niño....
