**Trader sentiment strongly favors a 14°C low for Mexico City on September 11, 2026, with an 86.5% implied probability, reflecting consensus from official observations and forecasts.** Mexico City’s high elevation (~2,240 m) produces relatively cool nights even in September’s rainy season, when average lows typically range 12–13°C amid frequent cloud cover and showers that limit radiative cooling. On this date, model consensus and station data pointed to a minimum near 14°C, with hourly readings bottoming around that level amid light rain and high humidity rather than clearer, colder conditions that could have pushed readings to 13°C or below. The elevated 48.5% probability on 13°C captures residual uncertainty in microsite variations or measurement timing, but the dominant 14°C outcome aligns with National Meteorological Service guidance and real-time monitoring. Upcoming resolution will hinge on final verified station data from sources like the Benito Juárez International Airport network, confirming the exact daily minimum against these climatological baselines.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
