Forecast models from sources like Yr.no and WeatherBug point to overnight lows of 12–15°C in Mexico City on August 21 amid the peak of the rainy season, with widespread cloud cover, scattered showers, and light northerly winds limiting radiative cooling at the city's 2,240 m elevation. Persistent humidity above 80% and thunderstorm activity help retain heat overnight while preventing sharp drops, though clearer breaks could allow temperatures to dip toward 12–13°C. Trader consensus clusters tightly around 13–15°C because ensemble forecasts show only minor disagreements on exact cloud timing and wind patterns, creating genuine uncertainty around the precise minimum rather than a single dominant outcome.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the Benito Juárez International Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Benito Juárez International Airport Station, available here: https://www.wunderground.com/history/daily/mx/mexico-city/MMMX.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
