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 4 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.Recent forecasts from multiple models, including Yr.no, Met Office, and WeatherBug, indicate a low of 7–9°C for Buenos Aires on September 4 under clear skies and moderate southwest winds following a cold front passage. These conditions favor radiational cooling overnight, aligning with the historical September average minimum near 9°C at Aeroparque. Trader sentiment reflects this consensus through elevated implied probabilities for 6–9°C outcomes, while the notable share assigned to 15°C or higher highlights residual model uncertainty or potential for warmer advection if winds shift. Updated official guidance from Argentina’s Servicio Meteorológico Nacional or the next ECMWF run could further refine overnight minimum expectations ahead of market resolution.
