Recent forecasts from multiple models converge on a high of 22–24°C for Mexico City on September 9, driven by persistent wet-season cloud cover, scattered afternoon convection, and light-to-moderate rain that limits surface heating at the city’s 2,240-meter elevation. Ensemble spreads arise mainly from variations in precipitation timing and cloud thickness: earlier or heavier showers favor the 23°C or lower bins by reducing insolation, while later or lighter activity allows brief clear spells that push readings to 24–25°C. Trader sentiment reflects this narrow uncertainty band, with the closely matched 24°C and 25°C-or-higher shares indicating weighted probabilities across official guidance and historical September climatology rather than any single outlier run. Updated model outputs closer to resolution will likely narrow the distribution.

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 9 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.Recent forecasts from multiple models converge on a high of 22–24°C for Mexico City on September 9, driven by persistent wet-season cloud cover, scattered afternoon convection, and light-to-moderate rain that limits surface heating at the city’s 2,240-meter elevation.
