The climate forecast for September to November 2025 predicts above-normal temperatures across the Northern Hemisphere and large parts of the Southern Hemisphere, with rainfall patterns similar to a moderate La Niña.

Despite the potential return of La Niña, global temperatures are still expected to rise due to ongoing human-induced climate change, with a 60% chance of La Niña conditions from October to December 2025 and little likelihood of El Niño developing during this period.

La Niña involves cooling sea surface temperatures in the central and eastern Pacific Ocean, increasing the risk of floods and droughts that can disrupt agriculture.

The World Meteorological Organization emphasizes the importance of using climate forecasts for preparedness and response, which can help save lives and reduce economic impacts across sectors such as agriculture, energy, health, and transportation.

Seasonal forecasts are crucial for sectors like agriculture, health, energy, and transportation, enabling policymakers and communities to prepare for weather-related risks.

Understanding phenomena like El Niño and La Niña is vital for climate prediction and disaster preparedness, helping to mitigate economic losses.

UN Secretary-General António Guterres has called for urgent climate action in 2025 to address the catastrophic impacts of record-breaking temperatures and ongoing climate change.

The World Meteorological Organization highlights that each of the past ten years has been among the warmest on record, underscoring the urgent need for climate action.

Governments are urged to incorporate climate forecasts into planning and response systems to better manage risks associated with La Niña and climate change.

ENSO influences global climate phenomena such as droughts, heavy rainfall, and temperature extremes, making seasonal forecasts essential for disaster preparedness.

Approximately 90% of excess heat from global warming is stored in the oceans, making ocean heat content a critical indicator of climate change.

The return of La Niña could have significant economic impacts across sectors like agriculture, energy, health, and transport, depending on how well preparedness measures are implemented.

Accurate seasonal forecasts and preparedness can help mitigate adverse effects and save thousands of lives through timely response actions.
