Forecast models from major centers indicate Mexico City’s overnight low on September 18 will likely settle near 13–15 °C, with the 14 °C outcome currently carrying the highest market-implied probability. At 2,240 m elevation, radiational cooling under clear or partly cloudy skies, combined with the city’s urban heat-island effect and surrounding basin topography, creates narrow differences between these thresholds. Ensemble guidance shows modest spread due to variable moisture from the Pacific and potential weak frontal passages, while historical September climatology places typical minima around 11–14 °C. Updated model runs tonight and early-morning observations will determine whether the low edges toward 13 °C or holds above 15 °C before 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 18 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.Forecast models from major centers indicate Mexico City’s overnight low on September 18 will likely settle near 13–15 °C, with the 14 °C outcome currently carrying the highest market-implied probability.
