Ongoing record ocean heat content and a strengthening, potentially very strong El Niño event are driving the 75% market-implied probability that 2026 finishes as the hottest year on record. Daily global sea-surface temperatures reached a new high of 21.1°C in late August—exceeding the 2024 peak—while year-to-date land-ocean averages through July rank among the top three in multiple datasets. Long-term greenhouse-gas forcing provides the baseline trend, and the developing El Niño adds substantial warmth through late 2026, with model consensus pointing to peak influence in October–December. NOAA and other agencies assign high likelihood of a top-five finish, though land temperatures have lagged slightly; final ranking hinges on how intensely the current El Niño couples with the ocean-atmosphere system in coming months.
