**Recent forecast consensus from models including ECMWF, GFS, and Yr.no points to persistent overnight cloud cover and light precipitation keeping Mexico City's minimum temperature on September 7 near 13–15°C, creating the close market split between sub-8°C and 18°C+ outcomes.** Atmospheric moisture from ongoing rainy-season patterns limits radiative cooling at the city's high elevation, while variable steering winds and model spread on exact cloud timing introduce uncertainty that traders weigh against typical September lows around 13–14°C. Updated runs from major agencies over the next 24–48 hours, particularly regarding rain timing and wind shifts, will likely refine these probabilities 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 7 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.**Recent forecast consensus from models including ECMWF, GFS, and Yr.no points to persistent overnight cloud cover and light precipitation keeping Mexico City's minimum temperature on September 7 near 13–15°C, creating the close market split between sub-8°C and 18°C+ outcomes.**
