La Niña may affect weather from September, says WMO

BERLIN — A return of La Niña may start to affect global weather patterns from September, the World Meteorological Organization (WMO) said on Tuesday, adding, however, that temperatures are still likely to be above average for large parts of the world.

The La Niña pattern involves the cooling of temperatures in the central and eastern Pacific Ocean, increasing the chance of floods and droughts, which can impact crops.

The latest WMO El Niño/La Niña Update indicates that?La Niña may develop from September 2025. Despite its temporary cooling influence,?above-average temperatures remain likely across much of the world.

Neutral conditions have persisted since March but may transition to La Niña conditions in the coming months, said the WMO in a statement.

Latest forecasts show a 55% likelihood of sea surface temperatures in the equatorial Pacific cooling to La Niña levels in the period from September to November, it said.

Seasonal forecasts and their impact on weather can translate into millions of dollars of economic savings for agriculture, energy, health and transport, said the WMO, adding thousands of lives can also be saved by preparing response actions. — Reuters
