Not yet. The World Meteorological Organization says the 2026 El Niño is firmly established and expected to become a very strong event, but it has not declared that a final historical record has already been set.
Observed weekly temperature anomalies in the central-eastern equatorial Pacific reached approximately 2.2°C to 2.6°C above average by mid-August. WMO models forecast further strengthening and a peak near the end of 2026, meaning the most extreme projections describe a possible future outcome.
The event could ultimately become the strongest in the modern observational record, but that depends on whether the forecast trajectory occurs. Headlines presenting the projected record as an established present-day fact omit this important distinction.
The 2026 El Niño may become record-breaking, but its final strength cannot be confirmed before the event reaches its peak.
World Meteorological Organization
The WMO says the event is still intensifying and is expected to peak toward the end of 2026, so its final strength has not yet been measured.

The WMO seasonal outlook forecasts a Niño 3.4 temperature anomaly of approximately 3.6°C for September through November, but this remains a forecast.

Reuters reports that the event could become the strongest recorded if its current trajectory continues, distinguishing the projection from an established record.

Yes. Solar edged past coal in installed capacity by the end of July 2026, but coal still generated much more electricity.
Yes. UNEP says long-term global warming is likely to cross 1.5°C within a few years, although future action can still limit the peak and duration.
