**Forecast models and real-time observations point to a peak temperature of 12–13°C in Buenos Aires on September 5, 2026, aligning with the market’s heavy weighting on those outcomes.** A recent cold front has established strong southerly to southwesterly winds of 15–30 km/h under mostly clear skies, limiting daytime warming in early spring conditions. Official guidance from agencies like the Servicio Meteorológico Nacional and international models consistently show afternoon maxima near 12–13°C, well below the September climatological average of about 19°C. Light cloud cover in some runs and minor variations in wind strength introduce limited upside risk toward 14°C, while the absence of warmer advection keeps lower readings improbable. Updated model runs and surface observations through the day remain the key inputs likely to refine final settlement.

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.
