**Persistent cloud cover, widespread rain, and Mexico City’s high elevation are anchoring trader expectations for a modest daily maximum near 23–24°C on September 6, 2026.** September marks the core of the rainy season, when afternoon convective storms and thick cloud decks routinely limit solar heating and cap temperatures. Current official and model guidance (including runs from international centers) points to a peak around 19–23°C under overcast skies with widespread precipitation, aligning closely with the long-term September average high of roughly 23–24°C at the city’s ~2,240 m elevation. The market’s heaviest weighting on 24°C (41.5%) and 23°C (26.5%), followed by 25°C (20%), reflects this consensus: traders appear to view 23–24°C as the most likely outcome given the moisture and cloud suppression, while still assigning meaningful probability to a slightly sunnier or less rainy window allowing a brief spike to 25°C. Lower outcomes below 22°C carry negligible implied odds, consistent with the absence of any strong cooling signals in recent observations or model runs. Upcoming model updates and real-time surface observations from the Benito Juárez airport station will be the key near-term drivers of any shifts in these probabilities.

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.
