Preliminary ERA5 reanalysis data indicate that global surface air temperatures on April 1-3, 2026, produced a peak daily 2-meter anomaly ranking as the third-hottest on record, driving trader consensus to price "3rd hottest" at 50.5% and "2nd hottest" at 29.5%, while deeming a new all-time record unlikely at just 7.5%. This positioning stems from persistent anthropogenic warming elevating the baseline—2025 marked the third-warmest year despite La Niña cooling—coupled with lingering high sea surface temperatures and early April westerly wind anomalies noted in NOAA's latest ENSO diagnostic, which favors neutral conditions through June (80% chance). March 2026's fourth-warmest ranking underscores the trend, though model uncertainties and potential data revisions leave room for shifts ahead of Copernicus' full April bulletin.

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.
