La Niña conditions emerged in the tropical Pacific in December. There’s a 59% chance La Niña will persist through February–April, followed by a 60% chance of neutral conditions in March–May. Read on for the recent observations that led us to declare the (long-awaited) onset of La Niña and lots of details for current and potential upcoming conditions.

There’s a 57% chance La Niña will develop soon. This is late for La Niña to arrive, and it’s very likely to be a weak event at most. However, even a weak event can influence temperature, rain, and snow patterns across the world. Today, we’ll take a tour through current conditions in the tropical Pacific and consider some of the things that might be interacting with La Niña’s development. First things first: what’s ENSO, and why do we care so much about it?

Forecasters continue to favor La Niña later this year, with an approximately 60% chance it will develop in September–November.

The tropical Pacific is still in neutral, but nature continues giving us signs that La Niña is on the way, and our La Niña Watch remains. Forecasters estimate a 71% chance that La Niña will emerge during September–November and expect it will persist through the Northern Hemisphere winter. A weak La Niña is the most likely scenario.

El Niño’s term is over, and La Niña is favored for the school year (79% chance for November–January). Our neutral summer break is well underway, so let’s pack our bags and hit the road. Summer schoolA quick primer for our newer visitors: El Niño and La Niña are opposite phases of the El Niño/Southern Oscillation (ENSO), a climate pattern that changes global atmospheric circulation.
