**Forecast models indicate overnight lows around 13–16°C for Mexico City on September 23, driven by persistent cloud cover, light rain, and the city's high elevation of roughly 2,240 meters.** Current conditions show mild, moist air with recent nighttime minima near 12–15°C amid the rainy season. Radiative cooling under clearer skies could push temperatures lower, while increased cloudiness and humidity from ongoing showers tend to moderate overnight drops. Model consensus from sources like GFS and ECMWF points to a low near 13–15°C, aligning with historical September averages of about 13°C. The closely matched market odds between ≤6°C and ≥16°C reflect genuine forecast uncertainty from variable steering patterns and precipitation timing, with traders weighing potential clear-sky cooling against rain-enhanced warmth ahead of final model updates.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Benito Juárez International Airport Station in degrees Celsius on 23 Sep '26.
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.**Forecast models indicate overnight lows around 13–16°C for Mexico City on September 23, driven by persistent cloud cover, light rain, and the city's high elevation of roughly 2,240 meters.**
