Tight market-implied odds for April 2026 ranking—2nd hottest at 43.5%, 4th or lower matching at 43.5%, 3rd at 42.5%, and 1st at 42.0%—stem from high uncertainty in ENSO evolution and intervening 2025 temperatures amid a relentless warming trend. Copernicus ERA5 data pegs April 2024 as the warmest on record (+0.77°C above 1991-2020 baseline), edging 2023 (+0.66°C) and 2020 (+0.54°C) for second and third. Rising radiative forcing boosts the baseline ~0.02°C annually, but ENSO swings (±0.4-0.6°C) dominate monthly ranks; a fading La Niña in 2025-26 could enable a neutral or weak El Niño to vault 2026 into top-three contention, while prolonged cool phases favor lower placement.

This market will resolve based on the data for the Global Land-Ocean Temperature Index for April 2026 versus the data points available for all other Aprils on record.
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.This market will resolve based on the data for the Global Land-Ocean Temperature Index for April 2026 versus the data points available for all other Aprils on record.
