**Strong El Niño conditions and sustained ocean heat content have anchored trader consensus on a 1.38–1.41 °C August 2026 global surface temperature anomaly above the 1850–1900 baseline.** Copernicus and Berkeley Earth analyses show July 2026 already at 1.56 °C, while record extra-polar sea-surface temperatures of 21.1 °C in late August—driven by an intensifying El Niño with Niño-3.4 anomalies exceeding +1.4 °C—support continued warmth without pushing the monthly mean into the next bin. Satellite lower-troposphere data from UAH confirm a +0.68 °C August anomaly relative to 1991–2020, consistent with surface estimates in the targeted range once converted to pre-industrial baselines. Upcoming final ERA5 and NOAA releases in mid-September, along with any revisions to ENSO strength, represent the main variables that could shift probabilities if model runs diverge sharply from current observations.

An anomaly within a named bracket for August 2026 is necessary and sufficient to resolve this market immediately once the data becomes available, regardless of whether the figure for August 2026 is later revised.
The primary resolution source for this market will be the figure found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Aug" in the row "2026" (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 August 2026 is provided by NASA by October 1, 2026, 11:59 PM ET, this market will resolve to the lowest range bracket.
