**Persistent cloud cover and high humidity at Mexico City's 2,240-meter elevation are anchoring overnight lows near 13–14°C on September 13.** Multiple forecast models show temperatures stabilizing around these values under overcast skies with light rain or showers, which reduce radiational cooling compared to clear nights. Dew points near 12–13°C further limit the drop, while light winds prevent stronger mixing or pooling of cold air. Historical September averages place typical lows around 10–12°C, but current conditions with 80–90% humidity and 90%+ cloud cover support the market's tight split between 13°C (51%) and 14°C (49.5%). Any brief clearing or model revisions on exact minimum timing could shift resolution between these closely matched outcomes.

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.
