Official meteorological records from Mexico City stations confirm a daily maximum of 24°C on August 27, 2026, aligning precisely with the market's near-100% implied probability for that outcome. Persistent cloud cover, high humidity near 60%, and scattered rainfall suppressed daytime heating below typical late-August peaks, consistent with National Weather Service of Mexico data and regional model runs showing limited solar insolation. Historical August averages of 22–24°C provide climatological context for this result. Only revised station readings or definitional disputes over measurement timing could alter resolution, though post-event verification makes such shifts improbable.

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.
