Recent observational data from Copernicus and ECMWF indicate September 2026 is tracking toward roughly 16.25°C globally, positioning it as the second-warmest September in the ERA5 record behind September 2023 amid a strengthening El Niño that has already driven August 2026 to the joint-hottest month ever at 16.96°C. Long-term anthropogenic warming plus Pacific heat release sustain elevated anomalies near +0.81°C relative to 1991–2020, yet seasonal cooling and model consensus keep the month short of overtaking the prior peak while comfortably ahead of other recent Septembers. Trader consensus at 97% implied probability for second place reflects these verified trends and narrow uncertainty ranges in ensemble forecasts; only substantial late-month warming revisions or data adjustments could realistically elevate it to first, while cooler-than-expected conditions would be required to drop it to third or lower.

Note: If September 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 for the relevant month (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 September 2026 is provided by NASA by the last day of the following month, 11:59:59 PM ET, a consensus of credible sources will be used to resolve this market.
