**Forecast consensus for Mexico City’s September 13 low centers on 13–14 °C, driven by the city’s 2,240 m subtropical highland climate where clear overnight skies enable rapid radiative cooling after daytime heating.** Multiple models show minimums near 13 °C around dawn under partly cloudy conditions with light rain possible, consistent with September climatology of roughly 10 °C average lows but elevated by current moisture and weak winds that limit mixing. Traders appear to weigh uncertainty in exact minimum timing and urban heat-island effects against historical diurnal ranges exceeding 10 °C. Differentiation among the tightly bunched 13–17 °C outcomes hinges on variables such as cloud-cover duration (thicker clouds trap heat, raising the floor by 1–2 °C), precipitation timing that can suppress cooling, and precise station measurements amid microclimate variations across the basin. Updated NHC/NOAA-style guidance or official Servicio Meteorológico Nacional reports tonight will likely sharpen these probabilities before resolution.

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.
