Official meteorological observations from Mexico City weather stations, including Benito Juárez International Airport data, recorded a daily maximum of 26°C on September 20, aligning with the market-implied consensus. This outcome reflects typical late-summer conditions in the highland basin, where afternoon temperatures often peak near 23–27°C amid variable cloud cover and scattered showers that moderate extremes. Model guidance from regional forecasts consistently projected highs in this range, with no significant warm-air advection or clear-sky amplification to push readings higher. While minor station-to-station variations or post-processing adjustments could theoretically alter the final reported value, the convergence of multiple sources makes deviation improbable at this stage.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=mmmx
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
