**Trader consensus heavily favors a 13°C low for Mexico City on September 15, 2026, at 87.5% implied probability, driven by consistent official forecasts and seasonal norms.** High-elevation subtropical highland conditions typically produce overnight lows near 13–14°C in mid-September, with diurnal ranges of 8–10°C under partly cloudy skies and light northerly winds. Multiple model runs and station data aligned on a minimum around 13°C, with no cold-air advection or clear-sky radiative cooling to push readings lower. Recent observations showed stable atmospheric pressure and humidity levels that limited further overnight drops, reinforcing the market's strong preference for this threshold over colder or warmer alternatives.

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 15 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.**Trader consensus heavily favors a 13°C low for Mexico City on September 15, 2026, at 87.5% implied probability, driven by consistent official forecasts and seasonal norms.** High-elevation subtropical highland conditions typically produce overnight lows near 13–14°C in mid-September, with diurnal ranges of 8–10°C under partly cloudy skies and light northerly winds.
