NOAA Declares El Niño Has Formed as Forecasters Expect Stronger Winter Conditions
NOAA forecasters declared El Niño conditions officially present in June 2023, confirming the arrival of a climate pattern expected to strengthen through the Northern Hemisphere winter and potentially influence weather across much of the globe.
The National Weather Service’s Climate Prediction Center issued an El Niño Advisory after observing warmer-than-average sea surface temperatures across the equatorial Pacific and atmospheric conditions consistent with the phenomenon’s development. Forecasters said confidence in continued strengthening increased as ocean temperatures rose and additional warming signals emerged across the Pacific basin.
At the time of the declaration, NOAA estimated an 84% chance the event would reach at least moderate strength and a 56% chance it would become strong during its peak phase.

El Niño is the warm phase of the El Niño-Southern Oscillation, a recurring climate cycle that can alter rainfall, temperature, and storm patterns around the world. Historically, strong El Niño events have been linked to increased flooding in some regions, drought in others, shifts in agricultural production, and elevated global temperatures.
The declaration generated substantial discussion among meteorologists, climate scientists, and emergency preparedness organizations. Online conversations focused on the possibility of new temperature records, impacts on hurricane activity, and potential consequences for water resources and food production.
NOAA emphasized that local outcomes vary and that El Niño does not produce the same effects everywhere. Still, the agency’s forecast signaled that one of the world’s most influential climate drivers had returned and was likely to shape weather conditions well into the following year.
