Fastrack · El Niño Expected to Intensify Into Very Strong Event

El Niño is strengthening rapidly across the tropical Pacific. Researchers say it could become one of the strongest events in recorded history.

2.7°C above average: the latest weekly Niño 3.4 index as of August 12, 2026.
Nearly 70% chance the event becomes the strongest El Niño on record by year-end.
Subsurface temperatures up to 490 feet deep exceed averages by more than 8°C in some areas.
100% model probability El Niño persists through March; 94% chance it continues through May.

Why it matters: El Niño shifts the jet stream south, reshaping who gets storms, warmth, or drought across the US this winter.

The northern US tier faces warmer, drier conditions; the southern tier faces wetter weather and potential winter storms.
A stronger event raises the odds expected patterns materialize, but NOAA says it does not guarantee historically intense impacts.
