Preliminary ERA5 data places April 1, 2026's global surface air temperature anomaly among the highest ever recorded, just shy of the top two peaks from 2024's midsummer heat dome, fueling trader consensus for a top-three all-time ranking at 87% market-implied odds, with 3rd hottest leading at 42.5%. Persistent elevated ocean heat content, despite the La Niña transition cooling El Niño extremes, sustains this positioning after January and February 2026 ranked fifth-warmest in ERA5 records and March shattered U.S. regional maxima. Forecasts from NOAA and Copernicus indicate above-normal early April warmth, but daily variability and reanalysis refinements introduce uncertainty; final ERA5 confirmations for April 2-3, due shortly, will determine if it surpasses prior benchmarks like July 22, 2024's 17.15°C absolute temperature.

Note: If April 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 "Apr" (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 April 2026 is provided by NASA by May 31, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.
