**Forecast models from multiple sources, including Worldmeteo, Yr.no, and others, converge on a maximum temperature of 17–18°C for Buenos Aires on September 4, 2026, under clearing skies and light southwesterly winds following showers on the 3rd.** This positions 18°C as the leading market outcome at 54.5% implied probability, with 19°C at 34.5% reflecting residual upside potential if daytime warming exceeds guidance. Spring climatology in the region favors highs near 19°C, yet current steering patterns and dry air advection keep readings slightly below average. Numerical weather prediction ensembles show limited spread, with resolution hinging on afternoon peak readings from official Servicio Meteorológico Nacional stations. Traders weigh these stable signals against typical model adjustments in the final 24 hours.

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 4 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.**Forecast models from multiple sources, including Worldmeteo, Yr.no, and others, converge on a maximum temperature of 17–18°C for Buenos Aires on September 4, 2026, under clearing skies and light southwesterly winds following showers on the 3rd.** This positions 18°C as the leading market outcome at 54.5% implied probability, with 19°C at 34.5% reflecting residual upside potential if daytime warming exceeds guidance.
