**Current forecasts and observations for Mexico City on September 10, 2026, show daytime highs centered around 22–23°C, aligning with the market’s leading 25°C outcome at 57.5% implied probability.** Mexico City’s high elevation of roughly 2,240 meters limits extreme heat, while September’s rainy season brings frequent afternoon convection, cloud cover, and showers that suppress peak temperatures by reducing solar insolation. Recent model runs and station data indicate light to moderate rain chances, with observed midday readings near 21–22°C under partly cloudy skies. Historical September averages hover near 23–25°C, but variability from steering patterns and moisture levels can shift highs by 2–3°C. Traders appear to price in modest upside potential if convection remains limited, placing lower odds on 26°C+ or sub-24°C scenarios.

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.
