Recent forecasts from meteorological agencies and models converge on a daily maximum of 24–26°C for Mexico City on September 5, aligning with the September climatological average high of 25°C at the city’s 2,240-meter elevation. Persistent cloud cover and a 50–70% chance of showers or thunderstorms—characteristic of the peak rainy season—limit solar heating and cap afternoon peaks, supporting the market’s heavy weighting toward 25–26°C. Minor model differences in timing of any brief clearing or convective activity introduce the modest probability assigned to 27°C or higher, while historical data show rare excursions above 28°C this early in the month under similar moisture patterns. Updated National Meteorological Service guidance and real-time observations will refine the precise peak before market resolution.

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.
