Trader consensus on Mexico City's lowest temperature for September 4 shows tight uncertainty, with the 17°C-or-higher outcome at 37% implied probability edging the 7°C-or-below bin at 36%. The main driver is divergence among short-range models on overnight radiative cooling and any evening precipitation, which strongly affects minimums at the city's 2,240-meter elevation where clear skies enable rapid heat loss. The ongoing rainy season can either enhance cooling through evaporative effects or moderate it via cloud cover and showers. Local Servicio Meteorológico Nacional observations and the next GFS/ECMWF runs will likely narrow the spread ahead of resolution.

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.
