The La Niña that developed in the second half of 2021 remains active in the tropical Pacific, although there are indications of its weakening, in terms of both oceanic and atmospheric parameters. The latest forecasts from the WMO Global Producing Centres of Long-Range Forecasts indicate a moderate chance (about 65%) of the current La Niña conditions continuing during March-May 2022, and about a 35% chance of their further weakening to El Niño/Southern Oscillation (ENSO)-neutral conditions. The La Niña event is forecast to dissipate thereafter, with ENSO-neutral becoming the most likely...

La Niña has developed for the second consecutive year and is expected to last into early 2022, influencing temperatures and precipitation. Despite the cooling influence of this naturally occurring climate phenomenon, temperatures in many parts of the world are expected to be above average because of the accumulated heat trapped in the atmosphere as a result of record high levels of greenhouse gases, according to the World Meteorological Organization (WMO).

Geneva, 9 September 2021 (WMO) - A weak La Niña event may re-emerge later in 2021 for the second consecutive year, with the risk that forecast precipitation patterns may exacerbate existing drought in some parts of the world and increase the risk of heavy rainfall and flooding in others. But despite La Niña’s cooling influence, temperatures over land areas are expected to be above average between September and November, especially in the northern hemisphere, according to the World Meteorological Organization.

Geneva, 1 st June 2021 (WMO) - The 2020-2021 La Niña event has ended and neutral conditions (neither El Niño or La Niña) are likely to dominate the tropical Pacific in the next few months, according to the World Meteorological Organization (WMO). Air temperatures are expected to be above average between June and August, especially in the northern hemisphere.

The 2020-2021 La Niña event has passed its peak, but impacts on temperatures, precipitation and storm patterns continue, according to a new update from the World Meteorological Organization (WMO). Despite the general cooling influence of La Niña events, land temperatures are expected to be above-normal for most parts of the globe in February-April 2021. La Niña appears to have peaked in October-November as a moderate strength event. There is a 65% likelihood that it will persist during February-April, with a 70% chance that the tropical Pacific will return to ENSO-neutral conditions by the...

Geneva, 14 January 2021 - The year 2020 was one of the three warmest on record, and rivalled 2016 for the top spot, according to a consolidation of five leading international datasets by the World Meteorological Organization (WMO). A naturally occurring cooling climate phenomenon, La Niña, put a brake on the heat only at the very end of the year.

As 2020 draws to an end, it closes the warmest decade (2011-2020) on record, according to the World Meteorological Organization. This year remains on track to be one of the three warmest on record, and may even rival 2016 as the warmest on record. The six warmest years have all been since 2015.

The World Meteorological Organization has strengthened its support to governments, the United Nations, and stakeholders in climate sensitive sectors to mobilize preparations and minimize impacts of La Niña.
