This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Benito Juárez International Airport Station in degrees Celsius on 24 Aug '26. 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 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.
Official forecasts from Mexico’s Servicio Meteorológico Nacional highlight unusually cold overnight conditions for August 24, with minimums of 8°C expected in higher-elevation boroughs such as Cuajimalpa and Magdalena Contreras and 9°C in several others, driven by radiative cooling under partly clear skies at roughly 2,300 m elevation. These values sit well below the month’s typical 12–13°C lows, reflecting recent model consensus and an active cold-air advection pattern that has already produced similar readings in prior days. Widespread showers and thunderstorms later in the day may limit further cooling but are unlikely to erase the early-morning minimum. The resulting market-implied odds place 9°C or below in the lead, consistent with the official temperature thresholds used for resolution.
