Forecast models indicate Mexico City’s peak temperature on August 28 will likely reach the mid-20s Celsius, with current consensus centering on 24–25 °C amid partly to mostly cloudy skies and scattered showers. High elevation near 2,240 m produces large diurnal swings, while August monsoon moisture and cloud cover suppress afternoon heating and increase variability across ensemble runs. Traders assign the highest implied probability to 25 °C (37.5 %), followed closely by 24 °C (28.5 %) and 26 °C (21.5 %), reflecting genuine forecast spread rather than strong directional bias. Updated model guidance and official station observations will determine resolution within the narrow temperature bands.

The resolution source for this market will be information from NOAA, specifically the highest 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.
