"The weak La Nina event that will appear in December 2024 is likely to only occur in a short time" - the latest update from the World Meteorological Organization, the United Nations said.
There is now a 60% chance of the weather returning to neutral conditions between March and May. The possibility of La Nina weakening and giving way to a neutral state is increased to 70% between April and June.
Last year, the World Meteorological Organization expected the reappearance of La Nina to help global temperatures drop slightly after many months at record highs. Previously, El Nino had covered the world for one year since June 2023.
However, La Nina does not seem to have a significant impact on global temperatures after 2024 was recorded as the hottest year in data history.
Despite the weak La Nina phenomenon, the World Meteorological Organization on March 6 pointed out, "January 2025 is the hottest January on record".
The latest seasonal global climate update report from the World Meteorological Organization notes, "Higher-than-normal sea surface temperatures are expected to continue to appear in all major oceans, except for the area near the equator in the eastern Pacific".
The World Meteorological Organization also predicts that "higher than average temperatures will occur in most parts of the world".
La Nina is a natural climate phenomenon that causes the temperature of the ocean surface in the tropical Pacific Ocean to drop, combined with wind, rain and changes in atmospheric pressure.
In many places, especially in tropical areas, La Nina has the opposite impact to El Nino, warming the ocean surface, leading to droughts and causing heavy rains in many other places.
The World Meteorological Organization believes that the possibility of El Nino developing again from now until June is "not significant".
