THE United Nations Organization announced that the cold weather La Ninia It may return between September and November, however, even if this happens, global temperatures are expected to remain above average.
La Ninia is a natural climate phenomenon that causes drop in temperature to central and east equatorial area of Pacific Ocean, while changing the standards of winds, pressure and rainfall. Conditions alternate magazines between La Ninia and the opposite phenomenon of El Ninio, with intermediate neutral periods.
According to the World Meteorological Organization (WMO) of the UN, after a short period of patient La Ninia, neutral conditions have prevailed since March. “There is a 55% chance that sea surface temperatures in the equatorial Pacific will fall to La Ninia levels” between September and November, he said. For the period October-December 2025 the probability is slightly increased to 60%. The chances of emerging El Ninium in the same period are very low.
La Ninia usually causes opposing climate effects from El Niniumwhich warms the surfaces of the oceans, leading to drought in some areas of the globe and in heavy rainfall in others. The prolonged La Ninia of the period 2020-2023, the first “triple” of the 21st century and only the third since 1950, has worsened drought and flooding phenomena.
However, despite its cold result, it failed to stop the sequence of extremely hot years. The last 10 years have been the warmest decade ever recorded, while temperatures remain at historically high levels even after El Niho’s retreat last year, with 2024 being the warmest year in the meteorological records.
WMO emphasized that phenomena such as La Ninia and El Ninio are now evolving in the context of anthropogenic climate change, “which increases global temperatures, intensifies extreme weather and affecting seasonal rainfall and temperature standards”.
According to its latest prognosis, the September-November period is expected to flow over average in much of the northern hemisphere, but also in extensive areas of the southern hemisphere.
