The primary driver behind current market-implied odds for Buenos Aires' highest temperature on September 11 is the expected arrival of a Sudestada, a persistent southeast wind pattern bringing cooler, humid maritime air from the Atlantic that limits daytime warming. Official Servicio Meteorológico Nacional forecasts and model consensus indicate mostly cloudy skies with maximums near 17°C amid strengthening gusts up to 50 km/h, following milder conditions the prior day. This setup aligns with historical September patterns where such events produce below-average highs around 16–18°C. Key variables include exact wind timing, cloud thickness affecting solar heating, and any model shifts in frontal progression that could allow brief warming to 19–20°C or suppress readings toward 16°C. Recent observational data from the past 48 hours show the pattern consolidating, though forecast uncertainty keeps probabilities distributed across several outcomes.

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 11 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.The primary driver behind current market-implied odds for Buenos Aires' highest temperature on September 11 is the expected arrival of a Sudestada, a persistent southeast wind pattern bringing cooler, humid maritime air from the Atlantic that limits daytime warming.
