According to meteorologists monitoring conditions in the East Pacific, La Nina - despite being in a weak state - still exists. However, there is a more than 50% chance that the phenomenon will end at the end of this spring.
La Nina is a cold phase of the Southern El Nino fluctuation phenomenon, also known as ENSO ( El Nino-Southern Oscillation), which occurs when the sea temperature in the equatorial Pacific Ocean drops at least 0.5 degrees Celsius below the seasonal average for about 7 months or more.
The latest weather forecast from the US Climate Prediction Center (CPC) said La Nina will continue to remain at a very weak level since the beginning of 2025. However, in recent weeks, unusually cold ocean waters in the Pacific have been gradually warming up, showing clear signs of weakness.
According to the CPC, with the current situation, the La Nina phenomenon is weakening and tends to shift to a neutral ENSO state in the coming weeks and months. This means that neither La Nina nor El Nino controls global weather.
If the neutral ENSO state goes as predicted, global weather could enter a period without clear dominance. This is especially important for the upcoming Atlantic hurricane season.
Typically, La Nina increases storm activity by reducing wind shear that hinders the development of tropical storms. If La Nina disappears, unfavorable conditions for storms may prevail, reducing the number and intensity of storms.
Although La Nina may disappear in the summer, experts predict that there is a about 50% chance of a neutral ENSO state continuing or La Nina could return this fall. However, predicting the development of ENSO in the spring period always faces many difficulties and unknowns are still very large.
Even if La Nina weakens, its effects on the atmosphere may last until early summer, continuing to affect global weather in the coming time.
