Recent forecasts indicate persistent cloud cover, showers, and thunderstorms across Mexico City on September 7, driven by a moist easterly flow and regional instability that limits daytime solar heating and caps the maximum temperature. Official guidance and ensemble models show highs clustered near 19–22°C, with the exact peak hinging on the timing and intensity of rainfall and the degree of afternoon clearing. This uncertainty explains the near-even market split between 23°C and 24°C-or-higher outcomes, as traders weigh model consensus against historical September averages around 23°C and the potential for brief breaks in the overcast to allow slightly warmer readings. Updated National Meteorological Service guidance and morning model runs will provide the key data ahead of market resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
