Strong El Niño conditions in the equatorial Pacific, with Niño 3.4 anomalies recently exceeding +2.0°C and forecasts for a historically intense event this fall and winter, represent the dominant near-term driver elevating August 2026 global surface temperatures. July 2026 tied for the second-warmest July on record at roughly 1.18°C above the 20th-century average, consistent with the multi-year warming trend and lagged ENSO influence on atmospheric temperatures. Preliminary NOAA and NASA data through mid-to-late August show anomalies tracking near 1.4°C above the 1850–1900 baseline, though final monthly values depend on the last week’s observations, dataset revisions, and processing differences across agencies. Trader consensus clusters tightly around 1.38–1.45°C because model spreads and day-to-day variability create genuine uncertainty within that narrow band, while the long-term anthropogenic baseline keeps sub-1.30°C outcomes highly improbable.

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.
