June 2024 update: La Niña likely by late summer
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.
content-drupal.climate.govHere’s the latest on El Niño vs La Niña based on recent authoritative updates.
What’s happening now
- ENSO conditions are moving toward neutral after recent El Niño. In late 2024 and into 2025, forecasters indicated a swing away from El Niño toward neutral, with potential beginnings of La Niña signals later in the year in some outlooks. This shift reflects the typical sequence where strong El Niño events are followed by weaker phases or La Niña, though timing and strength can vary by region and model consensus.[3][4]
Key sources and what they say
- World Meteorological Organization (WMO) updates: In mid-2024, WMO suggested a possible swing to La Niña later in the year, with probabilities increasing for La Niña during the late-year window, though uncertainty remained about strength and duration. This is part of the international effort to monitor and forecast ENSO phases and their broad climate impacts.[4]
- NOAA and Climate.gov overviews: After El Niño dominated through 2023-24, monitoring organizations noted the transition toward neutral conditions starting in 2024 and 2025, with continued watch for any renewed La Niña development later in 2025 or 2026. Updates emphasize that the atmosphere and ocean can re-align in various ways, affecting temperatures and precipitation globally.[5][10]
What this means for weather and climate
- Global temperature and precipitation patterns: El Niño tends to raise global average temperatures and shift rainfall patterns in many regions; a transition to neutral or La Niña typically cools global averages slightly and alters rainfall in various basins. Expect continued variability in extremes until a more definitive ENSO phase stabilizes.[8][5]
- Regional impacts can differ: Some regions may experience wetter conditions during La Niña, while others might face drought or heatwaves depending on shifts in jet streams and monsoon systems. Forecasts are most reliable when ENSO is definitively neutral or La Niña, but regional forecasts always incorporate other climate drivers as well.[5][8]
Practical takeaways
- If you’re planning agriculture, energy, or water resources, monitor the seasonal ENSO outlooks (NOAA Climate.gov, WMO ENSO updates) for the coming 3–6 months, as they give probabilistic guidance on whether neutral or La Niña conditions are likely to dominate and how that could influence heat, rainfall, and storm tracks.[8][5]
- For travelers and infrastructure planning in Texas and the southern U.S., ENSO shifts can influence winter-to-spring rainfall and temperature patterns; staying updated with the latest regional forecasts tied to ENSO status is prudent.[5]
