Preliminary ERA5 reanalysis from the Copernicus Climate Change Service positions May 1-3, 2026, global surface air temperatures as likely the second-hottest on record (59% implied probability), trailing 2024's peaks but surpassing 2025's second-place May, with 35% odds of outright first amid minor dataset discrepancies. This trader consensus stems from NOAA's recent ENSO update forecasting an 82% chance of El Niño emergence in May-July 2026—transitioning from lingering La Niña cooling—compounded by sustained record ocean heat content and a baseline ~1.45°C above 1850-1900 pre-industrial levels seen in April 2026's joint third-warmest ranking. Final Berkeley Earth and NOAA confirmations due late May could refine rankings, as reanalyses incorporate late-arriving observations.

Note: If May 2026 is tied for first, second, or third hottest with another year, it will qualify for the bracket it ties with.
The primary resolution source for this market will be the figures found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "May" (https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt). If NASA's "Global Temperature Index" is rendered permanently unavailable, other information from NASA may be used.
If no information for May 2026 is provided by NASA by June 30, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.
