June 2024 update: La Niña likely by late summer - Climate
The strong 2023-24 El Niño is over. Based on past events, does a strong El Niño portend a strong La Niña? Maybe, but it's complicated.
www.climate.govHere’s a concise update on the latest ENSO—El Niño vs La Niña—developments from reputable sources.
Current status at a glance
- El Niño ended in 2024; models and climate agencies have since tracked a potential move toward La Niña or neutral conditions, with forecasts often indicating a higher probability of La Niña or neutral states through 2025, though uncertainties remain. This follows the pattern that strong El Niño events are typically followed by a cooling phase or neutral period [source patterns: NOAA climate summaries, WMO updates].
Key takeaways from recent reports
- The World Meteorological Organization (WMO) and regional long-range forecast centers have repeatedly cautioned that the transition from El Niño to La Niña is not guaranteed to be immediate or uniform worldwide; shifts can occur at different times across basins and can be weaker or stronger than expected [WMO updates; NOAA ENSO pages]. This highlights continued variability and regional differences in how ENSO affects weather and climate anomalies globally.[3][5]
- NOAA and Climate.gov have noted that La Niña episodes, when they occur, tend to bring cooler global average temperatures and can influence regional patterns such as rainfall in the Americas, Australia, and parts of Africa and Asia; however, impacts are modulated by other climatic drivers and regional factors, so local effects can diverge from the global average trend [NOAA Climate.gov ENSO overview; WMO/IRI updates]. See NOAA’s ENSO pages for ongoing forecasts and discussions.[5][8]
What this could mean for you (practical implications)
- Weather planning and agriculture: If a La Niña pattern strengthens or persists, some regions may experience drier or wetter-than-average conditions depending on location, which could affect rainfall distribution, flood risk, and drought planning. Local meteorological services often adjust seasonal outlooks in response to emerging ENSO signals [WMO ENSO updates; NOAA climate blogs].
- Energy and infrastructure: Shifts in ENSO can influence heating/cooling demand and hydropower availability in regions influenced by Pacific weather patterns; planners should monitor official seasonal forecasts for guidance [NOAA ENSO pages; WMO updates].
