Recent forecasts from models like those referenced by NHC-aligned agencies and local monitoring point to an overnight low near 12–14°C for Mexico City on August 29, amid the ongoing rainy season at the city's 2,240-meter elevation. This creates tight market balance between the 19°C-or-higher and 9°C-or-below outcomes because cloud cover and scattered showers can suppress nocturnal radiative cooling while dry spells allow faster temperature drops after sunset. The highland location amplifies sensitivity to humidity, wind patterns, and precipitation timing, with historical August lows averaging 10–12°C but varying sharply day to day. Updated model runs and surface observations over the next 24 hours will likely refine these differentials ahead of market resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
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.
