**Forecast consensus points to a September 24 low near 13–15°C for Mexico City, reflecting typical late-summer diurnal ranges at its ~2,240 m elevation.** Nighttime radiative cooling under partly cloudy skies and light northeasterly winds is expected to produce minima around 12–15°C, consistent with recent official guidance from Mexican meteorological services and global models (GEM, ECMWF) showing 13°C overnight values. Scattered light rain or increased cloud cover could modestly limit cooling by trapping heat, while clearer periods might allow slightly lower readings. The closely matched market probabilities for extremes versus mid-range outcomes highlight model spread and uncertainty in exact station measurements (e.g., Tacubaya Observatory), with traders weighing historical September variability against the short 48-hour forecast window before resolution. Updated model runs and official briefings will likely refine these odds ahead of the 24th.

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 24 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 consensus points to a September 24 low near 13–15°C for Mexico City, reflecting typical late-summer diurnal ranges at its ~2,240 m elevation.** Nighttime radiative cooling under partly cloudy skies and light northeasterly winds is expected to produce minima around 12–15°C, consistent with recent official guidance from Mexican meteorological services and global models (GEM, ECMWF) showing 13°C overnight values.
