The article discusses a projected development of a potentially record-breaking El Niño by mid-year. This is driven by large pulses of unusually warm subsurface Pacific water surfacing.
It also highlights rising sea-surface temperatures and high confidence in the onset and intensification of El Niño. The broad climate implications could be significant if this warming strengthens.
Our summary will cover the drivers and uncertainties. It will also address regional and global impacts, as well as the ongoing context of fossil-fuel driven climate change.
What is driving the coming El Niño?
Subsurface Pacific warming and rising sea-surface temperatures are central to the forecast. Large pockets of heat stored beneath the surface are expected to move toward the surface, injecting warmth into the tropical Pacific and nudging the climate system toward an El Niño state.
Seasonal forecast models, along with the World Meteorological Organization, show rapidly rising sea-surface temperatures and high confidence in both the onset and further intensification of El Niño. If this heat release continues, it could significantly amplify global climate signals later in the year.
Spring forecasts: greater uncertainty
Spring forecasting is more uncertain than other seasons. While the event could become a super El Niño, that outcome is not guaranteed.
The atmosphere–ocean system is complex, and a range of factors can influence whether the warming crosses all the thresholds needed for a very intense El Niño. The risk of a record-breaking phase remains a major concern for climate-monitoring centers and policymakers.
What it could mean for global climate
If a substantial heat release occurs, it will supercharge the climate system and raise the likelihood of extreme heat waves and drought in some regions. The addition of atmospheric moisture from warmer oceans also increases the risk of more intense rainfall and heavier flooding in others.
These dynamics interact with long‑standing patterns of climate change driven by human activity.
- Record global temperatures are likely later this year or next as El Niño’s heat blends with ongoing anthropogenic warming.
- Global heat extremes could become more frequent, stressing water resources, agriculture, and urban infrastructure.
- The warmer oceans increase the energy available for storms and heavy rainfall events, even as certain regions face drought pressures.
- El Niño tends to suppress Atlantic hurricane activity, implying a potentially drier summer for the Caribbean and parts of the Atlantic with fewer tropical storms.
In the United States, forecasters expect a hotter-than-normal summer with significant heat waves and more frequent daily thunderstorms, particularly in the Southwest. The Amazon, already stressed by fires, logging, and drought, could face worsened conditions in 2026 under a strong El Niño.
Regional impacts: where the effects may be felt first
United States
Forecasts suggest a hotter-than-normal summer with more extreme heat events and an increase in daily thunderstorms across the Southwest. Urban heat islands, water resource stress, and power-grid demand could rise as heat records are challenged.
These conditions amplify public health risks and strain emergency response systems.
Atlantic and Caribbean regions
Historically, El Niño tends to reduce hurricane activity in the Atlantic basin. If this pattern holds, the Caribbean and parts of the Atlantic may experience a drier season with fewer tropical storms, potentially easing some flood and wind risks.
Regional climate variability means some areas could see unusual rainfall patterns, so preparedness remains essential.
South America and the Amazon
The Amazon watershed, already weakened by fires, logging, and drought, could face intensified stress under a strong El Niño. More heat and altered precipitation patterns threaten rainforest health, biodiversity, and regional livelihoods that rely on stable hydrological cycles.
Longer-term outlook and what this means for climate policy
Experts project that we could observe record global temperatures later this year or next as El Niño’s heat compounds with long-term anthropogenic warming. While El Niño is a cyclical phenomenon, the persistent danger comes from ongoing fossil-fuel driven climate change that will continue to raise baseline temperatures.
This reality underscores the need for sustained action on fossil fuels, climate resilience, and adaptation strategies to protect ecosystems, economies, and communities from escalating climate extremes.
What individuals and communities can do
Proactive planning and resilience-building are essential as El Niño aligns with ongoing warming.
Key steps include:
- Strengthen heat‑wave preparedness in urban areas and vulnerable populations.
- Enhance flood and drought monitoring, water management, and infrastructure planning.
- Support policies targeting greenhouse gas reductions and cleaner energy systems.
- Invest in climate-ready agriculture and wildfire management to mitigate crop and ecosystem risks.
