Trader consensus on Mexico City’s August 28 low clusters tightly around 13–14 °C because official station readings and model guidance converged on a minimum in that narrow band amid the city’s rainy-season regime. Persistent cloud cover, light rain, and elevated humidity suppressed radiative cooling overnight, while the urban heat island and 2,240 m elevation kept the floor from dropping further despite a passing cold front. Model runs from the Servicio Meteorológico Nacional and global ensembles showed only modest spread in boundary-layer moisture and wind, producing the near-even split between the two leading outcomes. Resolution hinges on the precise official minimum reported by the Mexico City observatory, where small differences in observation timing or siting can shift the final value by 1 °C.

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.
