Recent forecasts from models including ECMWF and GFS indicate a maximum of 17–19°C for Buenos Aires on September 8 under mostly clear skies and northerly winds, positioning 18°C as the market leader at 47% implied probability. This aligns with the climatological average high near 19°C for early September while reflecting cooler current conditions around 9–10°C on September 6 and a gradual warming trend. Trader consensus favors the 17–19°C band because model runs show limited variability in afternoon peaks, with only modest upside risk from stronger warming or downside from increased cloud cover. Updated guidance expected within the next 24–48 hours could refine these odds ahead of market resolution.

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.
