Official meteorological observations from stations in Mexico City confirmed a daily maximum of 22°C on September 7, 2026, under predominantly cloudy, rainy conditions that limited solar heating while aligning with seasonal norms for early September at the city's high elevation. Forecast models from sources including CONAGUA and international ensembles had projected highs near this value, with minimal spread once surface data arrived, reinforcing the market-implied odds through direct measurement rather than projection. Rare adjustments to preliminary readings or discrepancies across urban microclimates could theoretically alter the final figure, though such revisions remain uncommon once quality-controlled archives are published.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Benito Juárez International Airport Station in degrees Celsius on 7 Sep '26.
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.Official meteorological observations from stations in Mexico City confirmed a daily maximum of 22°C on September 7, 2026, under predominantly cloudy, rainy conditions that limited solar heating while aligning with seasonal norms for early September at the city's high elevation.
