Average sea surface and land temperatures across large parts of the world are forecast to be above normal in September-November, despite the expected absence of a full-blown El Niño event, according to the World Meteorological Organization (WMO).

A strong El Niño event during 2019 appears unlikely, according to a new World Meteorological Organization Update, which is based on forecast models and expert opinion from around the globe. Sea surface temperatures in the tropical Pacific Ocean have been at borderline to weak El Niño levels in April and early May 2019. Some El Niño-like atmospheric patterns have also been present.

There is a 50-60% chance of El Niño developing by May 2019, although it is not expected to be a strong event, according to the latest update from the World Meteorological Organization (WMO). Sea surface temperatures in the tropical Pacific were at or slightly below El Niño thresholds in January and early February 2019. Some El Niño-like atmospheric patterns also emerged around late January.

There is a 75-80% chance of an El Niño developing by February 2019, although it is not expected to be a strong event, according to the latest update from the World Meteorological Organization (WMO). Sea surface temperatures are already at weak El Niño levels in part of the tropical Pacific, although the corresponding atmospheric patterns have not yet materialized.

The powerful 2015-2016 El Niño has passed its peak but remains strong and will continue to influence the global climate, according to the latest update from the World Meteorological Organization. It is expected to weaken in the coming months and fade away during the second quarter of 2016. Eastern and central tropical Pacific Ocean surface temperatures were more than 2 degrees Celsius above average in late 2015, providing evidence that the 2015-16 El Niño is one of the strongest on record, comparable with the 1997-98 and 1982-83 events. It is too early to establish conclusively whether it was...

Current Situation and Outlook During the second half of 2016, tropical Pacific Ocean surface temperatures were at borderline weak La Niña/cool-neutral levels. Many atmospheric ENSO indicators also approached or exceeded...

A World Meteorological Organization committee of experts has announced new records for the highest temperatures recorded in the Antarctic Region as part of continuing efforts to expand a database of extreme weather and climate conditions throughout the world. Knowledge and verification of such extremes is important in the study of weather patterns, naturally occurring climate variability and human-induced climate change at global and regional scales.

A concerted international campaign to improve predictions of weather, climate and ice conditions in the Arctic and Antarctic has been launched to minimize the environmental risks and maximize the opportunities associated with rapid climate change in polar regions and to close the current gaps in polar forecasting capacity. The Year of Polar Prediction takes place from mid-2017 to mid-2019 in order to cover an entire year in both the Arctic and Antarctic and involves the World Meteorological Organization (WMO), Germany’s Alfred Wegener Institute (AWI) and a wide array of partners around the...

World Meteorological Organization initiatives to strengthen observations and predictions of weather, climate and ice conditions in response to rapid climate change in the Polar regions were showcased at the Arctic Circle Assembly in Iceland. WMO Secretary-General Petteri Taalas joined leading global experts at a plenary session on Observing and Responding to a Changing Arctic on the opening day of the assembly on 13 October.

Sea surface temperatures in the eastern tropical Pacific Ocean have recently cooled to weak La Niña levels. Similarly, most atmospheric indicators are now consistent with the early stages of a La Niña event. Climate models indicate that weak La Niña conditions are likely to persist into the first quarter of 2018. A return to ENSO-neutral conditions before early 2018 is less likely, while the emergence of El Niño before the second quarter of 2018 appears very remote. National Meteorological and Hydrological Services will continue to closely monitor changes in the state of ENSO over the coming...
