Recent forecast models point to a daily maximum of 21–23°C in Mexico City on September 8 amid the late rainy season, when persistent cloud cover and afternoon showers typically limit solar heating at the city’s 2,240-meter elevation. Historical September averages reach 23–24°C, yet current runs show slightly cooler conditions from enhanced convection and higher humidity, creating tight differentiation among 22–24°C outcomes. Model disagreements on exact rain timing and cloud thickness introduce the primary uncertainty, with new guidance expected to refine probabilities before resolution. Trader sentiment aggregates these variables into closely matched implied odds reflecting seasonal norms and short-term atmospheric variability.

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.
