Why is the US winter weather forecast trending?
Interest is rising because NOAA and other experts predict a record-breaking super El Niño, potentially the strongest in 75 years [2]. This phenomenon is expected to disrupt global weather, specifically impacting rainfall and temperatures during the coming winter [2].
What happened
- Earlier
The US experienced its hottest summer on record, partly due to El Niño [1].

What you need to know
A strong El Niño typically leads to a wetter winter for the southern US [2].
This event may be the most powerful recorded in over 75 years [2].
Strong El Niños often result in quieter Atlantic hurricane seasons but more activity in the Pacific [2].
The full extent of the super El Niño's impact remains to be seen [1].
Background
El Niño is a natural cycle occurring every few years, characterized by unusually warm waters in the central and eastern Pacific Ocean near the equator [1, 2].
This warming transfers heat into the atmosphere, which can shift global weather patterns, leading to events like flooding, intense storms, or severe droughts [1, 2].
Questions people ask
How does El Niño affect the southern US in winter?
It typically turbocharges the subtropical jet stream, which often results in a wetter winter for southern states [2].
What is a 'super El Niño'?
It is an exceptionally strong version of the periodic Pacific warming that can exceed the strength of previous recorded events [2].
