Recent model consensus from sources like GFS and ECMWF points to overnight lows of 13–14°C in Mexico City on September 17, driven by persistent cloud cover, light rain, and northerly flow associated with the late rainy season that limits radiative cooling at the city’s 2,240-meter elevation. These conditions align with historical September averages near 12–13°C while suppressing extremes through high humidity and urban heat retention. Trader emphasis on the 13°C and 14°C outcomes reflects this forecast stability, though slight model disagreements on clearing timing or wind strength could shift results toward 11–12°C or hold them above 15°C. Updated runs ahead of the overnight period will refine the exact minimum.

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.
