El Nino weather condition pattern likely to swing back to La Nina this year: UN weather condition firm

The El Nino weather condition pattern that can trigger extreme occasions such as wildfires and tropical cyclones is anticipated to swing back into normally cooler La Nina conditions later on this year, the World Meteorological Company (WMO) stated on Monday.

El Nino is a naturally happening warming of ocean surface area temperatures in the eastern and main Pacific, while La Nina is characterised by cold ocean temperature levels in the equatorial Pacific region and is linked to floods and drought.

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

Completion of El Nino does not indicate a pause in long-term environment change as our world will continue to warm due to heat-trapping greenhouse gases, said WMO Deputy Secretary-General Ko Barrett.

Remarkably high sea surface area temperature levels will continue to play a crucial role throughout the next months.

The past nine years have been the hottest on record regardless of the cooling result of La Nina that spanned from 2020 to early 2023, according to WMO.
