Recent forecast model runs for Mexico City show overnight lows on August 30 clustered between roughly 11–14 °C, with official Servicio Meteorológico Nacional guidance citing a 12–14 °C minimum under partly cloudy skies and light northeast winds. High elevation near 2,240 m promotes efficient nocturnal radiative cooling when cloud cover thins, yet scattered showers and elevated humidity from the ongoing rainy season limit temperature drops by trapping heat and raising dew points. Small differences in precipitation timing, wind speed, and boundary-layer mixing therefore separate the tightly bunched market outcomes; ensemble spread remains modest but sufficient to keep no single bin above 30 % implied probability. Updated model cycles and overnight observations will refine the exact minimum 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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
