Geneva, Dec 4 (EFE).- The World Meteorological Organization (WMO) indicated this Thursday that there is a 55% probability that the La Niña phenomenon, usually linked to a cooling of temperatures, will impact the climate between December and February, albeit in a weakened form.
In its update published this Thursday, the WMO clarifies that although La Niña is usually associated with a temporary drop in average global temperatures, some regions could continue to have hotter weather than normal.
As the year 2026 progresses, the WMO expects the planet to evolve towards neutral conditions, neither governed by La Niña nor by the opposite El Niño phenomenon, linked to temperature increases.
The probability of these neutral conditions will increase to 75% between February and April, according to the agency's periodic bulletin on these phenomena.
La Niña occurs due to a drop in water temperatures in the central and eastern Pacific Ocean, and is also accompanied by changes in tropical atmospheric circulation, accompanied by wind and rain.
The opposite El Niño phenomenon has not been observed by experts since 2024, which is so far the warmest year on record.
