The UK Met Office reports an unusually intense El Niño signal forming in the Pacific Ocean, with sea-surface temperature anomalies forecast to exceed 2.9°C and the event expected to dominate patterns from August to October 2026. Professor Adam Scaife stated he has never seen such an intense signal in forecasts, and the agency assesses 2027 as very likely to become the hottest year on record. A positive Indian Ocean Dipole is also projected alongside steady intensification noted by the World Meteorological Organization.
