Recent forecasts from sources including the Met Office and long-range models place Mexico City's maximum temperature on August 26 near 24–25°C, aligning with the market's tight clustering between those outcomes. This reflects typical late-summer conditions in the high-altitude Valley of Mexico, where intense solar heating interacts with moist air from the North American monsoon, often triggering afternoon convection and cloud cover that caps peaks. Historical August averages hover around 24°C, but day-to-day variability stems from the precise timing of showers, which can suppress highs by 1–2°C through evaporative cooling and reduced insolation. Model consensus remains moderate due to uncertainties in boundary-layer moisture and local orographic effects, with slight upside risk if clearer skies prevail midday.

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.
