**Latest model consensus from sources including GFS, ECMWF, and Mexican meteorological agencies points to an afternoon high in Mexico City on September 8 clustering between 22–25 °C.** This range reflects the city’s high elevation (approximately 2,240 m), which moderates temperatures year-round, combined with persistent September rainy-season dynamics—widespread cloud cover, high humidity, and afternoon convection—that typically suppress peak readings through evaporative cooling and reduced insolation. Recent observations show overcast skies and light rain on September 7 holding daytime maxima near 18–20 °C; forecast guidance indicates gradual clearing or only scattered showers on the 8th, allowing modest warming without full solar heating. Model spread and timing of any convective initiation introduce the observed market-implied uncertainty between a 24 °C peak and a 25 °C or higher outcome.

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 8 Sep '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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.**Latest model consensus from sources including GFS, ECMWF, and Mexican meteorological agencies points to an afternoon high in Mexico City on September 8 clustering between 22–25 °C.**
