🌊 In 2025, sea surface temperature (SST) outside of the polar regions ranked the third‑warmest on record.
The monthly average extra‑polar SST remained among the top four highest on record throughout the year, despite the absence of an El Niño event.
In the equatorial Pacific, temperatures moved from a short and weak La Niña at the end of 2024 and start of 2025, to near‑average conditions, and then back to a weak La Niña by October as cooler‑than‑average SSTs returned along the equator.
