Are We In El Nino Or La Nina 2025. Will El Nino Return In 2025 Layla Max Historical El Niño and La Niña Episodes Based on the ONI computed using ERSST.v5 ENSO Alert System Status: La Niña Advisory Synopsis: ENSO-neutral is favored to develop in the next month and persist through the Northern Hemisphere summer (62% chance in June-August 2025)
El Niño and La Niña What's the effect in California? from www.sfgate.com
La Niña conditions persisted through February, but forecasters expect ENSO-neutral conditions to develop in the next month and persist through the Northern Hemisphere summer. ENSO Alert System Status: La Niña Advisory Synopsis: La Niña conditions are expected to persist in the near-term, with a transition to ENSO-neutral likely during March-May 2025 (66% chance)
El Niño and La Niña What's the effect in California?
During February 2025, below-average sea surface temperatures (SSTs) weakened in the central and east-central equatorial Pacific Ocean [Fig La Niña is the cool phase of the El Niño/Southern Oscillation, or ENSO, a pattern of changes in the tropical Pacific Ocean and the atmospheric circulation over the tropical Pacific that persists for many months. However, we are noticing that if we use a relative ENSO index we probably would have declared this La Nina sooner
NOAA The Start of El Nino Has Officially Arrived Cattle Range. Big El Ninos generally lead to big heat discharge and a longer period for the heat to build back up in the tropics, leading to multi-year La Ninas and cold (blue) periods based on a threshold of +/- 0.5 ºC for the Oceanic Nino Index (ONI) [3 month running mean of ERSST.v5 SST anomalies in the Nino 3.4 region (5N-5S, 120-170W)].
