This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Minister Pistarini Intl Airport Station in degrees Celsius on 3 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest 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.
Forecast models from agencies including the National Meteorological Service of Argentina and international sources indicate a cold front will moderate temperatures in Buenos Aires on September 3, following September 2 highs near 21–23°C. Expect mostly cloudy conditions with possible showers and west-southwest winds, limiting daytime warming. Consensus high temperatures cluster around 17–19°C, with some runs allowing brief afternoon peaks near 20°C under partial clearing. This scientific outlook—driven by frontal passage, reduced insolation, and seasonal September averages of 19°C maximum—explains why traders assign 56% implied probability to 19°C and 27.5% to 20°C as the daily high, with lower outcomes reflecting downside risks from persistent cloud cover or heavier rain. Updated model runs and official observations tomorrow morning will further refine these market-implied odds.
