**Recent forecasts for Mexico City on September 9, 2026, point to a daytime maximum in the low-to-mid 20s °C, aligning with the market's emphasis on 23–25 °C outcomes.** Multiple models, including those from the Met Office and regional sources, project highs near 22–25 °C amid typical late-summer conditions at the city's high elevation of roughly 2,240 meters. Persistent cloud cover and scattered showers associated with the ongoing rainy season are expected to limit solar heating and cap temperatures, consistent with historical September averages around 24 °C. Current atmospheric patterns show no strong high-pressure ridge or clear-sky setup that would drive extremes above 25 °C or unusually cool readings below 22 °C. Short-range updates through September 7–8 will refine the exact peak, but the current ensemble consensus supports trader positioning around the most probable daily maximum near 24 °C.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Benito Juárez International Airport Station in degrees Celsius on 9 Sep '26.
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.**Recent forecasts for Mexico City on September 9, 2026, point to a daytime maximum in the low-to-mid 20s °C, aligning with the market's emphasis on 23–25 °C outcomes.** Multiple models, including those from the Met Office and regional sources, project highs near 22–25 °C amid typical late-summer conditions at the city's high elevation of roughly 2,240 meters.
