**Official meteorological observations from Argentina’s Servicio Meteorológico Nacional confirm a minimum temperature of 12°C in Buenos Aires on September 20, 2026, aligning with the market’s 99.5% implied probability for that exact outcome.** Multiple station reports and model-verified hourly data captured overnight lows near this threshold amid overcast skies, moderate southerly winds, and light rain that limited further cooling. Historical September averages (roughly 11–14°C) and the absence of cold-air advection or clear-sky radiational cooling reinforced this reading. The near-certainty in trader positioning reflects the completed observation window and cross-verified station consensus. Only an unlikely post-event data revision or redefinition of the measurement site could alter resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Minister Pistarini Intl Airport Station in degrees Celsius on 20 Sep '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=saez
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.**Official meteorological observations from Argentina’s Servicio Meteorológico Nacional confirm a minimum temperature of 12°C in Buenos Aires on September 20, 2026, aligning with the market’s 99.5% implied probability for that exact outcome.**
