Current numerical weather models, including GFS and ECMWF runs, indicate Mexico City highs of 24–26°C on September 23 under partly to mostly cloudy skies, light variable winds, and typical late-summer insolation at the city’s 2,240 m elevation. Afternoon convective activity associated with the end of the rainy season may limit peak warming, yet consensus favors temperatures near or above the 25°C threshold. Historical September averages center near 23–24°C, with rare excursions above 26°C under clearer or drier conditions. These forecast details and climatological baselines underpin trader positioning toward 25°C or higher outcomes ahead of final observational data.

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.
