Weather experts are warning that the winter of 2025-26 could turn out to be among the coldest in recent history, with mounting signs of La Niña returning.
This climate pattern, marked by cooler Pacific Ocean temperatures, often disrupts global air circulation and jet streams, leading to harsher winters, extended frost, and heavier snowfall.
According to the US Climate Prediction Center and other agencies, recent ocean temperature changes strongly suggest La Niña will take shape in the coming months.
If the forecasts prove accurate, many areas may face earlier cold spells, frequent frosts, and heavy snow in higher regions.
Meteorologists note that even a weaker La Niña can trigger sharp drops in temperature, affecting daily routines, farming, and local economies. The expected chill could also challenge countries less prepared for severe winter conditions.
