Trader consensus on Polymarket prices the peak ERA5 global 2-meter air temperature among April 1-3, 2026, as the 3rd hottest day on record (36.5%) or 2nd hottest (34.5%), reflecting sustained +1.5°C anomalies above the 1991-2020 baseline amid a La Niña-to-neutral ENSO transition. Copernicus data confirms January and February 2026 as fifth-warmest months globally, with March delivering record-shattering heat across western North America per World Weather Attribution analysis, fueling expectations these early spring days could rival 2024 summer peaks like July 22's 17.16°C benchmark. Differentiating factors hinge on short-term uncertainties: jet stream positioning, potential heat domes, and hemispheric contrasts, as seasonal WMO forecasts signal above-normal March-May land temperatures. Final ERA5 reanalysis (5-6 day lag) and ECMWF/GFS updates will resolve ambiguities.

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.
