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 1 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 which 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 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.
Forecast models from multiple agencies converge on a daytime high near 17°C for Buenos Aires on September 1, driven by southerly flow, high pressure, and partly cloudy skies that limit insolation while suppressing warm advection. Spring transition in the Southern Hemisphere brings gradual warming from August baselines near 16°C, yet current runs show limited afternoon mixing and no significant northerly return flow to push readings toward 19–21°C. Model consensus and historical analogs place the most probable peak in the 16–18°C range, with small spreads arising from exact timing of peak heating and boundary-layer depth rather than large-scale pattern shifts. Market-implied odds favoring 20–21°C therefore reflect residual uncertainty ahead of final observational confirmation on resolution day.
