GENEVA - The El Nino weather pattern that can cause extreme events such as wildfires and tropical cyclones is forecast to swing back into generally cooler La Nina conditions later this year, the World Meteorological Organization said on Monday.

El Nino is a naturally occurring warming of ocean surface temperatures in the eastern and central Pacific, while La Nina is characterized by cold ocean temperatures in the equatorial Pacific region and is linked to floods and drought.

The past nine years have been the warmest on record despite the cooling effect of La Nina that spanned from 2020 to early 2023, according to WMO

WMO said there was a 60 percent chance that La Nina conditions would take hold between July to September, and a 70 percent chance of them occurring between August and November.

"The end of El Nino does not mean a pause in long-term climate change as our planet will continue to warm due to heat-trapping greenhouse gases," said WMO Deputy Secretary-General Ko Barrett.

"Exceptionally high sea surface temperatures will continue to play an important role during the next months."
