Recent forecasts from multiple models, including those aligned with National Meteorological Service guidance, point to a daily maximum near 23–25°C for Mexico City on September 20 amid the rainy season's typical afternoon cloud build-up and scattered showers. These conditions, combined with the city's 2,240-meter elevation and northeasterly flow, limit solar heating and favor a peak in the mid-20s rather than sustained warmer readings. Recent observations from September 19 reached 24–27°C under partly clearer skies, providing a close analog that supports trader emphasis on 26°C (54.5% implied probability) while allowing modest upside to 27°C or higher if convection is delayed. Official station data and final model consensus updates through the afternoon will resolve the exact threshold.

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.
