Recent forecasts from Mexican meteorological sources and international models converge on a daily high of 22°C in Mexico City on September 7, driven by persistent cloud cover exceeding 80-90% and a 65-90% chance of light rain or showers that suppress daytime heating. This aligns with the rainy-season climatology for the region, where average September maxima hover near 25°C but frequently fall lower under overcast conditions and light winds. Official monitoring by CONAGUA and similar agencies provides the resolution benchmark, with trader consensus heavily weighting the most probable observed peak. A realistic challenge would require unexpected clearing that boosts solar insolation enough to push readings to 23°C or above, though current model runs show low likelihood of such shifts before the measurement window closes.

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 7 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.Recent forecasts from Mexican meteorological sources and international models converge on a daily high of 22°C in Mexico City on September 7, driven by persistent cloud cover exceeding 80-90% and a 65-90% chance of light rain or showers that suppress daytime heating.
