Current forecasts for Buenos Aires on August 31 project daytime highs of 16–18°C under partly cloudy skies with light easterly winds, consistent with late-winter climatology where average maxima hover near 17–18°C. Trader consensus favoring 19–21°C reflects model spread in afternoon clearing, potential shortwave warming, or slight underestimation of insolation as high pressure builds. Differentiating these outcomes hinges on precise timing of cloud cover, dew-point recovery from overnight lows near 10°C, and boundary-layer mixing—factors that official Servicio Meteorológico Nacional observations will resolve. With forecasts stable and no incoming fronts expected, probabilities remain sensitive to the next 24–48 hours of model updates.

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 31 Aug '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.
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.Current forecasts for Buenos Aires on August 31 project daytime highs of 16–18°C under partly cloudy skies with light easterly winds, consistent with late-winter climatology where average maxima hover near 17–18°C.
