Recent forecasts from meteorological agencies show Mexico City's overnight low stabilizing near 13–15°C on September 22, driven by the city's 2,240-meter elevation, moderate cloud cover, and light northerly winds that limit radiative cooling overnight. These conditions align with typical September climatology, where morning minima rarely fall below 12°C absent a strong cold front. Model consensus highlights minor uncertainties in boundary-layer moisture and urban heat retention, which could shift the exact minimum by 1–2°C depending on observation timing and station location. Trader sentiment, reflected in closely matched odds around 13–15°C, weighs these variables against historical baselines while awaiting final verified readings.

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 22 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.Recent forecasts from meteorological agencies show Mexico City's overnight low stabilizing near 13–15°C on September 22, driven by the city's 2,240-meter elevation, moderate cloud cover, and light northerly winds that limit radiative cooling overnight.
