The forecast is strong, but it is still a forecast

NOAA's 10 September ENSO Diagnostic Discussion said El Niño was strengthening and gave a greater than 90% chance of a very strong event during Northern Hemisphere autumn and winter 2026–27. The discussion reported warming across the eastern equatorial Pacific. That supports the central direction of our video, while the word “historic” in the title should be understood as a possibility rather than an observed final ranking.

What the index does and does not say

El Niño measures a coupled ocean-atmosphere pattern in the tropical Pacific. A warmer Niño-3.4 reading is important, but strength categories depend on the specified index and averaging period. A single weekly or monthly anomaly is not interchangeable with a season-long index. A strong event can shift the odds of rain and temperature in many regions; it does not guarantee a specific storm, drought or city forecast.

Readers making local decisions should use their national weather service for near-term warnings. NOAA's next diagnostic update may revise the probability or expected peak strength as new observations arrive.
