Recent forecasts for Mexico City on September 21 indicate daytime highs most likely between 23–25°C under overcast skies with light drizzle or rain possible, driven by persistent cloud cover and northerly winds at the city’s 2,240-meter elevation. These conditions typically suppress maximum temperatures below seasonal peaks, aligning with climatological September averages near 24°C. Model runs show modest variability in peak timing and intensity, with some guidance allowing brief clearing that could push readings to 26–27°C while others favor steadier moisture keeping values lower. The closely matched market odds around 26–27°C reflect this narrow range of uncertainty in afternoon observations, with resolution hinging on official station data amid typical late-summer atmospheric patterns.

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.
