Current forecasts for Mexico City on September 9 indicate overnight lows near 12–14°C amid persistent cloud cover, scattered showers, and high humidity typical of the late rainy season. Mexico City’s 2,240-meter elevation produces a pronounced diurnal range, where afternoon convection and evaporative cooling from tropical moisture often moderate nighttime temperatures while limiting radiational cooling under overcast skies. Model consensus from recent runs shows limited spread around these values, though steering patterns from distant tropical systems and the strengthening El Niño could shift moisture or clear intervals enough to push the minimum a few degrees either way. Historical September lows average near 12–13°C, providing a baseline against which traders weigh the near-term data releases.

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.
