El Niño has strengthened and is likely to peak as the strongest on record, with potential to push global temperatures higher into 2027. Forecasts warn of hotter years ahead, increased weather extremes, and regional impacts, including droughts and floods, while Atlantic Niña patterns could curb tropical storms.
Record‑level and near‑record May temperatures have been reported across multiple regions this week — parts of England and Russia have hit unusually high temps while the eastern US has recorded low‑90s — even as eastern Australia is facing a major rain band. Forecasts show brief, intense heat will give way to fronts or rain in most places; Australia is also seeing El Niño odds rise for winter.
El Niño has formed in the Pacific and is expected to strengthen through late 2026, with a 63% chance of reaching a very strong level. Forecasts warn of hotter global temperatures and extreme weather, while impacts will vary by region. Scientists urge preparation and climate action as nations monitor evolving conditions.
