**Recent official forecasts position an 18–19°C high as the most likely outcome for Buenos Aires on August 27, 2026, consistent with the market’s leading probabilities (19°C at 38.5%, 18°C at 28.5%).** Multiple sources, including the Servicio Meteorológico Nacional (SMN) and international models, project a daytime maximum near 17–18°C under mostly cloudy skies and southeast winds associated with an approaching frontal system. Persistent cloud cover and scattered showers or thunderstorms—especially in the morning—limit surface heating and keep the daily peak modest, aligning with late-winter climatology where average highs hover around 16–17°C. Some model runs allow brief clearing or slightly warmer advection to push the reading to 19°C, which explains its narrow edge in trader-implied odds. Lower probabilities for 20°C+ reflect the risk that stronger instability or heavier rain could cap temperatures further, while sub-17°C outcomes remain possible only if the front arrives earlier or cloudiness is more extensive than currently expected. Updated model guidance and real-time observations through the morning of the 27th will be the key variables for any last-minute shifts in market sentiment.

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 27 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.**Recent official forecasts position an 18–19°C high as the most likely outcome for Buenos Aires on August 27, 2026, consistent with the market’s leading probabilities (19°C at 38.5%, 18°C at 28.5%).** Multiple sources, including the Servicio Meteorológico Nacional (SMN) and international models, project a daytime maximum near 17–18°C under mostly cloudy skies and southeast winds associated with an approaching frontal system.
