Saira Imran Climate experts have raised alarms that La Niña 2025 could bring the coldest winter the world has seen in decades. International weather agencies, including the U.S. Climate Prediction Center, have issued an alert, warning of freezing winds, early snowfalls, and extended cold waves across several regions.
This weather pattern, known as La Niña, is not new, but its possible return this year has sparked concern. Experts say the world must prepare for what could be a tough and long winter.
What is La Niña?
La Niña is a climate pattern that occurs when sea surface temperatures in the central and eastern Pacific Ocean drop below normal levels. This cooling affects wind circulation and alters the jet stream.
The result is a chain reaction that impacts global weather. Winters become harsher, snow increases, and cold winds sweep across continents. Even weaker forms of La Niña can significantly reduce global temperatures, showing how powerful this pattern can be.
Why La Niña 2025 Matters?
Experts warn that if La Niña 2025 develops fully, many regions may experience:
- Severe cold waves
- Early and heavy snowfall
- Longer freezing periods
Such conditions could strain energy supplies, disrupt travel, and affect food production. Meteorologists highlight that this year’s La Niña has the potential to be stronger than usual, making preparation more important than ever.

Past Impact of La Niña
History shows that La Niña has always brought noticeable changes to global weather. In previous decades, La Niña led to:
- Record-breaking cold winters in North America
- Unusually harsh winters in Northern Europe
- Long freezing spells in Central Asia
These examples remind us that La Niña is not a local issue but a worldwide phenomenon.
Current Ocean Signs Indicate Trouble
Recent observations of the Pacific Ocean reveal falling sea temperatures. This is an early sign of La Niña forming. Experts believe there is a 60–70% chance that La Niña 2025 will strengthen over the next few months.
If this trend continues, the winter ahead could be more severe than anything seen in recent memory.
Global Effects Beyond Winter
La Niña does not only affect cold weather. Its impact spreads across the world:
- Australia and Southeast Asia: Heavy rainfall and floods
- East Africa and Southwestern U.S.: Severe drought conditions
- Atlantic Ocean: Stronger and more frequent hurricanes
This means the effects of La Niña 2025 will reach far beyond snow and cold, touching lives across multiple continents.
How La Niña 2025 Could Affect Daily Life?
A strong La Niña event could change many aspects of everyday life. Experts predict:
- Energy consumption will rise due to heating demands
- Agricultural production may suffer from frost and drought in different regions
- Transport and travel could face major disruptions
- Health risks like flu and cold-related illnesses may increase
These challenges highlight the importance of early planning and preparation for households, businesses, and governments alike.
Will Pakistan Be Affected?
A major question for people in South Asia is whether Pakistan will face the direct impact of La Niña 2025. According to Anjum Nazir Zaigham, Deputy Director of the Pakistan Meteorological Department, La Niña will not directly affect Pakistan.
However, he stressed that weather systems are interconnected. While the direct effects may not be felt in Pakistan, the ripple effects in global trade, agriculture, and energy markets could still influence the country indirectly.

La Niña 2025 is a Reminder
The return of La Niña 2025 is a reminder of how closely linked our climate systems are. From freezing winters to floods, droughts, and hurricanes, its impact will be global. Experts urge people and governments to prepare now to reduce risks in the coming months.
As history shows, La Niña events are powerful and unpredictable. With early signs already visible in the Pacific Ocean, the world must brace for what could be the coldest winter in decades.
