British forecasters warn that a developing El Niño—an ocean–atmosphere warming pattern in the eastern Pacific—could become the strongest such event in living memory. Reporting from outlets citing the UK’s Met Office says the current warming is likely to be the largest El Niño since the 19th century.
El Niño is described as a periodic rise in sea surface temperatures in the eastern Pacific linked to weakening trade winds. Sources note it occurs naturally every two to seven years and typically lasts around nine months, though timing and impacts can vary. The outlets present largely consistent assessments, with coverage focused on how unusually intense the pattern may be and how it could affect global weather.
While both reports converge on the forecast strength and the role of Met Office guidance, they emphasize different context: one highlights the “since the 19th century” comparison, while the other also reiterates the scientific basics of how El Niño forms and its general timing.
