Current forecast models, including GEM and GFS runs as of September 22, indicate overnight lows in Mexico City around 12–15°C for September 23, driven by clear to partly cloudy skies, light winds under 5 mph, and radiative cooling at the city's 2,240-meter elevation. This aligns with typical late-September climatology, where average minimums range 12–14°C amid moderating high pressure and low precipitation chances. Trader sentiment reflects model consensus on these mid-range values alongside resolution uncertainty from station-specific measurements and potential microclimate variations, while the elevated probabilities on extremes highlight divergent model outputs or tail risks from unexpected cloud cover or wind shifts. Updated NHC-equivalent regional guidance and final hourly observations will refine the exact minimum before market resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Benito Juárez International Airport Station in degrees Celsius on 23 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.Current forecast models, including GEM and GFS runs as of September 22, indicate overnight lows in Mexico City around 12–15°C for September 23, driven by clear to partly cloudy skies, light winds under 5 mph, and radiative cooling at the city's 2,240-meter elevation.
