Later in 2026, climate experts predict changes in worldwide weather once El Nino takes hold. Global temps may climb, according to projections. The UK could face sharper cold snaps during winter months instead. Regional effects will differ, but warming trends appear likely overall.
One reason scientists point to? A fading La Nina, part of the broader El Nino-Southern Oscillation pattern. Australia's weather agency sees that cool phase winding down now, opening space for balanced ocean temps ahead of a possible flip to warmer ones. Across the Pacific, U.S. forecasters estimate just under two out of three chances for an El Nino start during midyear, lasting into late 2026.
