Trader sentiment clusters tightly around 13–14°C for Mexico City’s August 26 minimum because current ensemble forecasts from the Servicio Meteorológico Nacional and global models (GFS, ECMWF) converge on overnight lows near the August climatological average of 13.3°C, with limited spread from persistent cloud cover and scattered convective rain during the wet season. These conditions moderate radiative cooling at the city’s 2,240 m elevation while the urban heat island effect prevents deeper drops below 12°C. Traders assign lower weight to 19°C+ or sub-10°C outcomes given the narrow historical range (rarely outside 11–15°C) and stable steering patterns that limit clear-sky extremes overnight. Updated model runs and local station observations from the Mexico City basin ahead of the overnight minimum will refine 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
