Forecast models from the Servicio Meteorológico Nacional and international ensembles show moderate uncertainty for Buenos Aires on September 2, with maximum temperatures hinging on the timing of a weakening high-pressure ridge versus possible southerly flow. Warmer 24°C or 23°C scenarios reflect northerly advection of subtropical air and reduced cloud cover boosting daytime heating, while cooler 21°C outcomes align with earlier frontal passage or increased marine layer influence. Historical early-spring baselines near 20–22°C, combined with current ENSO-neutral conditions, support this tight clustering of trader-implied odds around the central range. Updated model runs and official briefings over the next 48 hours will likely refine the most probable maximum.

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 2 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 the Servicio Meteorológico Nacional and international ensembles show moderate uncertainty for Buenos Aires on September 2, with maximum temperatures hinging on the timing of a weakening high-pressure ridge versus possible southerly flow.
