The current year is expected to conclude as the 3rd warmest in the instrumental record (94% chance), behind 2023 and 2024 and slightly above the long-term trend.
Further, it is unlikely that 2025 will exceed the 1.5 °C threshold.

IRI/CPC long-range forecasts expect that this new La Niña will likely dissipate by early 2026, with increasing odds of a new El Niño event in mid to late 2026.

After recent neutral conditions, NOAA has officially noted the return of La Niña conditions, marked by relative cooling in the Pacific.
The current La Niña is expected to be weak and short-lived, but may increase the chance of Arctic outbursts in North America this winter.

October 2025 was 1.52 ± 0.08 °C (2.73 ± 0.14 °F) above the 1850-1900 average.
This is the 3rd warmest October in the instrumental record (i.e. since 1850), behind only the El Niño boosted warmth in 2023 and 2024.
