After just a few months, La Niña conditions have ended and the tropical Pacific has returned to neutral conditions. Our blogger gives you the scoop on La Niña's end and the forecast for the rest of 2025.
ENSO Blog
A blog about monitoring and forecasting El Niño, La Niña, and its impacts.
It’s March Madness, ENSO style! Our blogger discusses why the North American precipitation pattern this past winter looked more like the response to a moderate-strength La Niña than to a weak event.
La Niña conditions are waning, and a transition to ENSO-neutral is favored in the next month.
A new paper looked at 20 years work of real-time ENSO Model forecasts and found some interesting patterns. Did you know models found it pretty freaking hard to predict the onset of La Nina events?
Weak La Niña conditions continued in January, but a transition to ENSO-neutral in the near future is likely.
Why no one should expect a perfect match between what happens during a La Niña winter and the expected La Niña pattern. But knowing whether it may be a El Niño or La Niña winter is still useful!
After a long wait, La Niña conditions developed in December. What makes this La Niña unusual?
Officially, the ocean is lagging, but the tropical atmosphere is already looking La Niña-like.
Big things sometimes come in small packages, and our blogger explains why this winter’s expected weak La Niña might have a bigger precipitation impact than usual.
The expected La Niña has been slow to develop. There's still a 57% chance it will emerge soon, and the atmosphere is already looking a bit like La Niña. Our blogger discusses some of the climate conditions at work in the tropical Pacific.
