Recent forecasts for Mexico City on August 31 indicate daily highs clustered in the 20–26°C range, with multiple models converging on 23–25°C amid typical late-summer conditions. Persistent cloud cover, high humidity, and frequent afternoon thunderstorms associated with the regional rainy season are limiting solar heating and capping peak temperatures near or slightly below the August climatological average of around 22–24°C. Official guidance from sources such as the Met Office and regional ensembles points to scattered convection and easterly flow that favor modest warming before midday, followed by cooling showers. This pattern supports the market’s emphasis on 24°C and 23°C as the most probable outcomes, while the 20% probability assigned to 26°C or higher reflects residual uncertainty if breaks in cloud cover allow greater insolation. Updated model runs and satellite observations over the next 48 hours will refine these projections ahead of market resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Benito Juárez International Airport Station in degrees Celsius on 31 Aug '26.
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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the 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.Recent forecasts for Mexico City on August 31 indicate daily highs clustered in the 20–26°C range, with multiple models converging on 23–25°C amid typical late-summer conditions.
